    • Abstract: Publication date: Available online 15 November 2014

      Author(s): Dragan Simić , Vasa Svirčević , Svetlana Simić
      Business stability, quality, safety, supply chain flexibility and cost optimization have an increasing role in companies that strive to stay and survive in the market competition. A wise supplier choice becomes ever more important prerequisite for the success of any company. This paper presents a novel hybrid model for supplier assessment and selection, based on hybrid solution including genetic algorithm (GA) and harmony search algorithm (HSA). The chosen data set presents original data which is used for assessment in “Lames” company. The results show that HSA & GA value constraint model is slightly more restricted than other discussed models, and separates, much better and with greater precision, poor companies from the good ones in business environment.

  • An efficient Reverse Distribution System for solving sustainable supply
           chain network design problem
    • Abstract: Publication date: Available online 18 November 2014

      This paper deals with a sustainable supply chain network design problem (SSCNDP) arising in the public sector. In the considered SSCNDP, given a manufacturer, a set of m potential distribution centers (DCs) having a given distinct capacity, and a set of n customers, each one with a particular demand, we have to select the number and the location of the DCs necessary to supply demands to all the customers and the allocation of the customers to these DCs such that the installation and transportation costs integrated with greenhouse gas (GHG) emissions are minimized. Due to the complexity of the problem, an efficient Reverse Distribution System (RDS) consisting of several improved classical heuristic algorithms is proposed. The developed approaches were tested and promising results were obtained on benchmark instances based on the literature, involving between 10 and 50 distribution centers and between 10 and 100 customers.

  • Conventional controller design based on Takagi–Sugeno fuzzy models
    • Abstract: Publication date: Available online 15 November 2014
      Source:Journal of Applied Logic
      Author(s): Jana Nowaková , Miroslav Pokorný , Martin Pieš
      Although it is long since the first PID controller design method was developed, new methods are still being created and no general applicable method has been found. The paper extends the set of designing methods of PID controllers. Design methods can be divided into classic (analytical tuning methods, optimization methods etc.) and not so common fuzzy knowledge based methods. In this case, a conjunction of both methods is presented. The classic design methods (Ziegler–Nichols step response method and Chien, Hrones and Reswick design method) are used for achieving the knowledge of fuzzy knowledge based design methods. The fuzzy knowledge based design methods are based on Takagi–Sugeno model. It is defined as a class of systems for which – using the new proposed method – the settling time is shorter or the settling time is nearly the same but without overshoot, which could be also very useful. The proof of efficiency of the proposed methods and a numerical experiment is presented including a comparison with the conventional methods (simulated in the software environment Matlab-Simulink).

      This paper reports a real application whose task was to recognize characters printed on metal ingots. The problem is that surface of ingots is very uneven — ingots are hot or cold, cut by rough instrument, the printing machine can be worn down, etc. In this paper, we present two original recognition methods: the first one is based on application of mathematical fuzzy logic and the second one is based on representation of an image by a fuzzy-valued function. Results of these methods are compared with a simple neural network classifier and few other common methods.

      Author(s): Ivan Zelinka , Donald David Davendra , Roman Šenkeřík , Michal Pluháček
      This paper discusses predictive control of chemical reactor by means of evolutionary algorithm named SOMA – the Self-Organizing Migrating Algorithm, that can be classified as swarm intelligence or memetic algorithm. The SOMA algorithm was used for multiple input–multiple output control of reactor model after static optimization. The MIMO control was defined for 5 inputs and 2 outputs with total number of 12 unknown variables. This paper is based on simulation results from optimization of static parameters that has been used to set up reactor for its evolutionary control.

  • Information retrieval from hospital information system: Increasing
           effectivity using swarm intelligence

      This paper details the process of mining information from a hospital information system that has been designed approximately 15 years ago. The information is distributed within database tables in large textual attributes with a free structure. Information retrieval from these information is necessary for complementing cardiotocography signals with additional information that is to be implemented in a decision support system. The basic statistical overview (n-gram analysis) helped with the insight into data structure, however more sophisticated methods have to be used as human (and expert) processing of the whole data were out of consideration: over 620,000 text fields contained text reports in natural language with (many) typographical errors, duplicates, ambiguities, syntax errors and many (nonstandard) abbreviations. There was a strong need to efficiently determine the overall structure of the database and discover information that is important from the clinical point of view. We have used three different methods: k-means, self-organizing map and a self-organizing approach inspired by ant-colonies that performed clustering of the records. The records were visualized and revealed the most prominent information structure(s) that were consulted with medical experts and served for further mining from the database. The outcome of this task is a set of ordered or nominal attributes with a structural information that is available for rule discovery mining and automated processing for the research of asphyxia prediction during delivery. The proposed methodology has significantly reduced the processing time of loosely structured textual records for both IT and medical experts.

  • Implementation and testing of a soft computing based model predictive
           control on an industrial controller

      This work presents a real time testing approach of an Intelligent Multiobjective Nonlinear-Model Predictive Control Strategy (iMO-NMPC). The goal is the testing and analysis of the feasibility and reliability of some Soft Computing (SC) techniques running on a real time industrial controller. In this predictive control strategy, a Multiobjective Genetic Algorithm is used together with a Recurrent Artificial Neural Network in order to obtain the control action at each sampling time. The entire development process, from the numeric simulation of the control scheme to its implementation and testing on a PC-based industrial controller, is also presented in this paper. The computational time requirements are discussed as well. The obtained results show that the SC techniques can be considered also to tackle highly nonlinear and coupled complex control problems in real time, thus optimising and enhancing the response of the control loop. Therefore this work is a contribution to spread the SC techniques in on-line control applications, where currently they are relegated mainly to be used off-line, as is the case of optimal tuning of control strategies.

  • An approach to abstract argumentation with recursive attack and support
    • Abstract: Publication date: Available online 17 December 2014
      Source:Journal of Applied Logic

      This work introduces the Attack-Support Argumentation Framework (ASAF), an approach to abstract argumentation that allows for the representation and combination of attack and support relations. This framework extends the Argumentation Framework with Recursive Attacks (AFRA) in two ways. Firstly, it adds a support relation enabling to express support for arguments; this support can also be given to attacks, and to the support relation itself. Secondly, it extends AFRA's attack relation by allowing attacks to the aforementioned support relation. Moreover, since the support relation of the ASAF has a necessity interpretation, the ASAF also extends the Argumentation Framework with Necessities (AFN). Thus, the ASAF provides a unified framework for representing attack and support for arguments, as well as attack and support for the attack and support relations at any level.

  • Towards a logical belief function theory
    • Abstract: Publication date: Available online 17 December 2014
      Source:Journal of Applied Logic
      Author(s): Laurence Cholvy
      This paper presents a version of belief function theory in which masses are assigned to propositional formulas and which allows the modeller to consider integrity constraints. It also provides three combination rules which apply within this framework. It proves that the initial version of belief function theory and its extension to non-exclusive hypotheses are two particular cases of this proposal. It finally shows that, even if this framework is not more expressive than the belief function theory as defined by Dempster and Shafer, its interest resides in the fact that it offers the modeller a rich language to express its beliefs, i.e., the propositional language.

      This paper introduces a general logical framework for reasoning about diffusion processes within social networks. The new “Logic for Diffusion in Social Networks” is a dynamic extension of standard hybrid logic, allowing to model complex phenomena involving several properties of agents. We provide a complete axiomatization and a terminating and complete tableau system for this logic and show how to apply the framework to diffusion phenomena documented in social networks analysis.

  • Simplified method based on an intelligent model to obtain the extinction
           angle of the current for a single-phase half wave controlled rectifier

      With the aim of calculating the extinction angle of the current of a single-phase half wave controlled rectifier with resistive and inductive load, present work shows a method to obtain a regression model based on intelligent methods. This type of circuit is a typical non-linear case of study that requires a hard work to solve it by hand. To create the intelligent model, a dataset has been obtained with a computational method for the working range of the circuit. Then, with the dataset, to achieve the final solution, several methods of regression were tested from traditional to intelligent types. The model was verified empirically with electronic circuit software simulation, analytical methods and with a practical implementation. The advantage of the proposed method is its low computational cost. Then, the final solution is very appropriate for applications where high computational requirements are not possible, like low-performance microcontrollers or web applications.

  • Division by zero in non-involutive meadows
    • Abstract: Publication date: March 2015
      Source:Journal of Applied Logic, Volume 13, Issue 1
      Author(s): J.A. Bergstra , C.A. Middelburg
      Meadows have been proposed as alternatives for fields with a purely equational axiomatization. At the basis of meadows lies the decision to make the multiplicative inverse operation total by imposing that the multiplicative inverse of zero is zero. Thus, the multiplicative inverse operation of a meadow is an involution. In this paper, we study ‘non-involutive meadows’, i.e. variants of meadows in which the multiplicative inverse of zero is not zero, and pay special attention to non-involutive meadows in which the multiplicative inverse of zero is one.

  • Naturalizing logic Errors of reasoning vindicated: Logic reapproaches
           cognitive science
    • Abstract: Publication date: March 2015
      Source:Journal of Applied Logic, Volume 13, Issue 1
      Author(s): Lorenzo Magnani
      A complete revision of mainstream logic is an urgent task to be achieved. This revision will be able to bring logic into a creative rapprochement with cognitive science. This can be achieved by trying to do for logic what over forty years ago Quine and others attempted for epistemology. It is necessary to propose a “naturalization” of the logic of human inference. This paper deals with an examination of how the naturalization process might go, together with some indication of what might be achieved by it. To assist the reader in understanding the naturalization of logic I will take advantage of my own research on the concept of abduction, which vindicates the positive cognitive value of the fallacy of the affirming the consequent thanks to the so-called EC-model (Eco-Cognitive model), and of the recent book Errors of Reasoning: Naturalizing the Logic of Inference (2013) [86], by John Woods. While this paper certainly aims at promoting the research program on the naturalization of logic, it also further advocates the placement of abduction in the research programmes of logic, and stresses to what extent our contemporary philosophical and logical tradition is indebted towards Charles Sanders Peirce, a thinker often praised for his productivity but whose quality and importance are too often overlooked.

  • Runtime verification using the temporal description logic ALC-LTL
           revisited
    • Abstract: Publication date: Available online 6 September 2014
      Source:Journal of Applied Logic
      Author(s): Franz Baader , Marcel Lippmann
      Formulae of linear temporal logic (LTL) can be used to specify (wanted or unwanted) properties of a dynamical system. In model checking, the system's behaviour is described by a transition system, and one needs to check whether all possible traces of this transition system satisfy the formula. In runtime verification, one observes the actual system behaviour, which at any point in time yields a finite prefix of a trace. The task is then to check whether all continuations of this prefix to a trace satisfy (violate) the formula. More precisely, one wants to construct a monitor, i.e., a finite automaton that receives the finite prefix as input and then gives the right answer based on the state currently reached. In this paper, we extend the known approaches to LTL runtime verification in two directions. First, instead of propositional LTL we use the more expressive temporal logic ALC -LTL, which can use axioms of the Description Logic (DL) ALC instead of propositional variables to describe properties of single states of the system. Second, instead of assuming that the observed system behaviour provides us with complete information about the states of the system, we assume that states are described in an incomplete way by ALC -knowledge bases. We show that also in this setting monitors can effectively be constructed. The (double-exponential) size of the constructed monitors is in fact optimal, and not higher than in the propositional case. As an auxiliary result, we show how to construct Büchi automata for ALC -LTL-formulae, which yields alternative proofs for the known upper bounds of deciding satisfiability in ALC -LTL.

      Author(s): Marcello D'Agostino , Mario Piazza , Gabriele Pulcini
      In this paper we introduce a new deductive framework for analyzing processes displaying a kind of controlled monotonicity. In particular, we prove the cut-elimination theorem for a calculus involving series-parallel structures over preorders which is built up from multi-level sequents, an interesting and promising variant of Gentzen-style sequents. More broadly, our purpose is to provide a general, syntactical tool for grasping the combinatorics of non-monotonic processes.

  • Products of Modal Logics and Tensor Products of Modal Algebras
    • Abstract: Publication date: Available online 27 August 2014

      Author(s): D. Gabbay , Ilya Shapirovsky , Valentin Shehtman
      One of natural combinations of Kripke complete modal logics is the product, an operation that has been extensively investigated over the last 15 years. In this paper we consider its analogue for arbitrary modal logics: to this end, we use product-like constructions on general frames and modal algebras. This operation was first introduced by Y. Hasimoto in 2000; however, his paper remained unnoticed until recently. In the present paper we quote some important Hasimoto's results, and reconstruct the product operation in an algebraic setting: the Boolean part of the resulting modal algebra is exactly the tensor product of original algebras (regarded as Boolean rings). Also, we propose a filtration technique for Kripke models based on tensor products and obtain some decidability results.

  • Constraint LTL Satisfiability Checking without Automata
    • Abstract: Publication date: Available online 28 July 2014
      Source:Journal of Applied Logic
      Author(s): Marcello M. Bersani , Achille Frigeri , Angelo Morzenti , Matteo Pradella , Matteo Rossi , Pierluigi San Pietro
      This paper introduces a novel technique to decide the satisfiability of formulae written in the language of Linear Temporal Logic with both future and past operators and atomic formulae belonging to constraint system D (CLTLB( D ) for short). The technique is based on the concept of bounded satisfiability, and hinges on an encoding of CLTLB( D ) formulae into QF-EU D , the theory of quantifier-free equality and uninterpreted functions combined with D . Similarly to standard LTL, where bounded model-checking and SAT-solvers can be used as an alternative to automata-theoretic approaches to model-checking, our approach allows users to solve the satisfiability problem for CLTLB( D ) formulae through SMT-solving techniques, rather than by checking the emptiness of the language of a suitable automaton. The technique is effective, and it has been implemented in our Z ot formal verification tool.

We derive a representation theorem for functions satisfying this principle and investigate its relationship with the first order principles of Regularity and Super Regularity.

  • A postulate-based analysis of comparative preference statements
    • Abstract: Publication date: Available online 15 July 2014
      Source:Journal of Applied Logic
      Author(s): Souhila Kaci , Namrata Patel
      There has been a growing interest in the study of preferences for their utility in solving problems related to decision making. Most of the preference representation languages developed in the literature are based on comparative preference statements since they offer a simple and intuitive way for expressing preferences. They can be further interpreted following different semantics, imparting a greater flexibility on how outcomes can be compared. So far the main objective has been to rank-order the set of outcomes given a set of comparative preference statements and one or several semantics. Tackling this problem from a different angle, we look into the behavioural aspects of the preference semantics and statements by attempting to formalise the intuition behind them using postulates studied in preference logics and non-monotonic reasoning. We select the postulates w.r.t. three criteria: coherence, syntax independence and inference. Thus, our analysis provides a means to determine those properties that are satisfied for a given preference semantics.

      This article introduces a deontic logic which aims to model the Canadian legal discourse. Category theory is assumed as a foundational framework for logic. A deontic deductive system DDS is defined as two fibrations: the logic for unconditional obligations OL is defined within a Cartesian closed category on the grounds of an intuitionnistic propositional action logic PAL and an action logic AL , while a logic for conditional normative reasoning CNR is defined as a symmetric closed monoidal category. A typed syntax and typed arrows are used to define properly DDS . We show how it can solve the paradoxes of deontic logic and we provide some examples of application to legal reasoning.

      Within an axiomatic framework, we prove that the existence of faster than light (FTL) particles is consistent with (does not contradict) the dynamics of Einstein's special relativity. The proof goes by constructing a model of relativistic dynamics where FTL particles can move with arbitrary speeds. To have a complete picture, we not only construct an appropriate model but explicitly list all the basic assumptions (axioms) we use.

      I claim that an argument from the philosophy of statistics can be improved by using Carnapian inductive logic. Gelman and Shalizi [9] criticise a philosophical account of how statisticians ought to choose statistical models which they call ‘the received view of Bayesian inference’ and propose a different account inspired by falsificationist philosophy of science. I introduce another philosophical account inspired by Carnapian inductive logic and argue that it is even better than Gelman and Shalizi's falsificationist account.

      Author(s): Benedikt Bollig , Aiswarya Cyriac , Paul Gastin , Marc Zeitoun
      We develop a general framework for the design of temporal logics for concurrent recursive programs. A program execution is modeled as a partial order with multiple nesting relations. To specify properties of executions, we consider any temporal logic whose modalities are definable in monadic second-order logic and which, in addition, allows PDL-like path expressions. This captures, in a unifying framework, a wide range of logics defined for ranked and unranked trees, nested words, and Mazurkiewicz traces that have been studied separately. We show that satisfiability and model checking are decidable in EXPTIME and 2EXPTIME, depending on the precise path modalities.

  • Information, confirmation, and conditionals
    • Abstract: Publication date: Available online 26 May 2014
      Source:Journal of Applied Logic
      Author(s): Peter Milne
      Loosely speaking, a proposition adds the more information to corpus b, the greater the proportion of possibilities left open by b that it rules out. Plausible qualitative constraints lead to the result that any measure of information-added is a strictly decreasing rescaling of a conditional probability function sending 1 to 0. The two commonest rescalings are − log P and 1 − P . In a similar vein, e is favourable evidence for hypothesis h relative to background b if h rules out a smaller proportion of the possibilities left open by b and e jointly, than left open by b alone. In terms of the underlying probability measure, this secures the familiar positive relevance conception of confirmation and that f is more favourable evidence for h than e iff h rules out a smaller proportion of the possibilities left open by b and f jointly than left open by b and e jointly. In these terms, a measure of confirmation should be a function of the information added by h to b ∧ e and to b, decreasing with the first and increasing with the second. When e = h , the possibilities that drop out as we narrow the focus with e are exactly the possibilities left open by b but excluded by h. Thus the extent to which h confirms h relative to b is a measure of the information h adds to b. Given a measure I of information added, we can think of I ( a c , b ) − I ( a , b ) as a measure of the “deductive gap”, relative to b, between a and a ∧ c . When I ( a , b ) = − log P ( a b ) , I ( a c , b ) − I ( a , b ) = − log P ( c a b ) , the amount of information the indicative conditional ‘if a then c’ adds to b on Ernest Adams' account of that conditional. When I ( a , b ) = 1 − P ( a b ) , I ( a c , b ) − I ( a , b ) = I ( a ⊃ c , b ) where a ⊃ c is a material conditional. What, if anything, can be said in general about “information theoretic” conditionals obtained from measures of information-added in this way' We find that, granted a couple of provisos, all satisfy modus ponens and that the conditionals fall victim to Lewis-style triviality results if, and only if, I ( a ∧ ¬ a , b ) = ∞ (as happens with −

      This paper examines two aspects of propositional probabilistic logics: the nesting of probabilistic operators, and the expressivity of probabilistic assessments. We show that nesting can be eliminated when the semantics is based on a single probability measure over valuations; we then introduce a classification for probabilistic assessments, and present novel results on their expressivity. Logics in the literature are categorized using our results on nesting and on probabilistic expressivity.

  • Probabilities of counterfactuals and counterfactual probabilities
    • Abstract: Publication date: Available online 7 February 2014
      Source:Journal of Applied Logic
      Author(s): Alan Hájek
      Probabilities figure centrally in much of the literature on the semantics of conditionals. I find this surprising: it accords a special status to conditionals that other parts of language apparently do not share. I critically discuss two notable ‘probabilities first’ accounts of counterfactuals, due to Edgington and Leitgeb. According to Edgington, counterfactuals lack truth values but have probabilities. I argue that this combination gives rise to a number of problems. According to Leitgeb, counterfactuals have truth conditions-roughly, a counterfactual is true when the corresponding conditional chance is sufficiently high. I argue that problems arise from the disparity between truth and high chance, between approximate truth and high chance, and from counterfactuals for which the corresponding conditional chances are undefined. However, Edgington, Leitgeb and I can unite in opposition to Stalnaker and Lewis-style ‘similarity’ accounts of counterfactuals.

      Bayesians understand the notion of evidential support in terms of probability raising. Little is known about the logic of the evidential support relation, thus understood. We investigate a number of prima facie plausible candidate logical principles for the evidential support relation and show which of these principles the Bayesian evidential support relation does and which it does not obey. We also consider the question which of these principles hold for a stronger notion of evidential support.

      This paper sheds new light on the subtle relation between probability and logic by (i) providing a logical development of Bruno de Finetti's conception of events and (ii) suggesting that the subjective nature of de Finetti's interpretation of probability emerges in a clearer form against such a logical background. By making explicit the epistemic structure which underlies what we call Choice-based probability we show that whilst all rational degrees of belief must be probabilities, the converse doesn't hold: some probability values don't represent decision-relevant quantifications of uncertainty.

      We investigate some finitely-valued generalizations of propositional dynamic logic with tests. We start by introducing the n + 1 -valued Kripke models and a corresponding language based on a modal extension of Łukasiewicz many-valued logic. We illustrate the definitions by providing a framework for an analysis of the Rényi–Ulam searching game with errors. Our main result is the axiomatization of the theory of the n + 1 -valued Kripke models. This result is obtained through filtration of the canonical model of the smallest n + 1 -valued propositional dynamic logic.

      Here-and-there models and equilibrium models were investigated as a semantical framework for answer-set programming by Pearce, Valverde, Cabalar, Lifschitz, Ferraris and others. The semantics of equilibrium logic is given in an indirect way: the notion of an equilibrium model is defined in terms of quantification over here-and-there models. We here give a direct semantics of equilibrium logic, stated for a modal language embedding the language of equilibrium logic.

  • A propositional linear time logic with time flow isomorphic to ω2
    • Abstract: Publication date: June 2014

      Author(s): Bojan Marinković , Zoran Ognjanović , Dragan Doder , Aleksandar Perović
      Primarily guided with the idea to express zero-time transitions by means of temporal propositional language, we have developed a temporal logic where the time flow is isomorphic to ordinal ω 2 (concatenation of ω copies of ω). If we think of ω 2 as lexicographically ordered ω × ω , then any particular zero-time transition can be represented by states whose indices are all elements of some { n } × ω . In order to express non-infinitesimal transitions, we have introduced a new unary temporal operator [ ω ] (ω-jump), whose effect on the time flow is the same as the effect of α ↦ α + ω in ω 2 . In terms of lexicographically ordered ω × ω , [ ω ] ϕ is satisfied in 〈 i , j 〉 -th time instant iff ϕ is satisfied in 〈 i + 1 , 0 〉 -th time instant. Moreover, in order to formally capture the natural semantics of the until operator U, we have introduced a local variant u of the until operator. More precisely, ϕ u ψ is satisfied in 〈 i , j 〉 -th time instant iff ψ is satisfied in 〈 i , j + k 〉 -th time instant for some nonnegative integer k, and ϕ is satisfied in 〈 i , j + l 〉 -th time instant for all 0 ≤ l < k . As in many of our previous publications, the leitmotif is the usage of infinitary inference rules in order to achieve the strong completeness.

      The aim of this article is to construct a deontic logic in which the free choice postulate allow (Ross, 1941) [11] would be consistent and all the implausible result mentioned in (Hanson, in press) [5] will be blocked. To achieve this we first developed a new theory of action. Then we build a new deontic logic in which the deontic action operator and the deontic proposition operator are explicitly distinguished.

  • A logical framework for privacy-preserving social network publication

      Social network analysis is an important methodology in sociological research. Although social network data are valuable resources for data analysis, releasing the data to the public may cause an invasion of privacy. In this paper, we consider privacy preservation in the context of publishing social network data. To address privacy concerns, information about a social network can be released in two ways. Either the global structure of the network can be released in an anonymized way; or non-sensitive information about the actors in the network can be accessed via a query-answering process. However, an attacker could re-identify the actors in the network by combining information obtained in these two ways. The resulting privacy risk depends on the amount of detail in the released network structure and expressiveness of the admissible queries. In particular, different sets of admissible queries correspond to different types of attacks. In this paper, we propose a logical framework that can represent different attack models uniformly. Specifically, in the framework, individuals that satisfy the same subset of admissible queries are considered indiscernible by the attacker. By partitioning a social network into equivalence classes (i.e., information granules) based on the indiscernibility relation, we can generalize the privacy criteria developed for tabulated data to social network data. To exemplify the usability of the framework, we consider two instances of the framework, where the sets of admissible queries are the ALCI and ALCQI concept terms respectively; and we exploit social position analysis techniques to compute their indiscernibility relations. We also show how the framework can be extended to deal with the privacy-preserving publication of weighted social network data. The uniformity of the framework provides us with a common ground to compare existing attack models; while its generality could extend the scope of research to meet privacy concerns in the era of social semantic computing.

  • Empiricism, probability, and knowledge of arithmetic: A preliminary
           defense
    • Abstract: Publication date: Available online 31 December 2013
      Source:Journal of Applied Logic
      Author(s): Sean Walsh
      The topic of this paper is our knowledge of the natural numbers, and in particular, our knowledge of the basic axioms for the natural numbers, namely the Peano axioms. The thesis defended in this paper is that knowledge of these axioms may be gained by recourse to judgements of probability. While considerations of probability have come to the forefront in recent epistemology, it seems safe to say that the thesis defended here is heterodox from the vantage point of traditional philosophy of mathematics. So this paper focuses on providing a preliminary defense of this thesis, in that it focuses on responding to several objections. Some of these objections are from the classical literature, such as Fregeʼs concern about indiscernibility and circularity (§ 2.1), while other are more recent, such as Bakerʼs concern about the unreliability of small samplings in the setting of arithmetic (§ 2.2). Another family of objections suggests that we simply do not have access to probability assignments in the setting of arithmetic, either due to issues related to the ω-rule (§ 3.1) or to the non-computability and non-continuity of probability assignments (§ 3.2). Articulating these objections and the responses to them involves developing some non-trivial results on probability assignments (Appendix A–Appendix C), such as a forcing argument to establish the existence of continuous probability assignments that may be computably approximated (Theorem 4 Appendix B). In the concluding section, two problems for future work are discussed: developing the source of arithmetical confirmation and responding to the probabilistic liar.

      A logic for specifying probabilistic transition systems is presented. Our perspective is that of agents performing actions. A procedure for deciding whether sentences in this logic are valid is provided. One of the main contributions of the paper is the formulation of the decision procedure: a tableau system which appeals to solving systems of linear equations. The tableau rules eliminate propositional connectives, then, for all open branches of the tableau tree, systems of linear equations are generated and checked for feasibility. Proofs of soundness, completeness and termination of the decision procedure are provided.

  • A neural cognitive model of argumentation with application to legal
           inference and decision making

      Formal models of argumentation have been investigated in several areas, from multi-agent systems and artificial intelligence (AI) to decision making, philosophy and law. In artificial intelligence, logic-based models have been the standard for the representation of argumentative reasoning. More recently, the standard logic-based models have been shown equivalent to standard connectionist models. This has created a new line of research where (i) neural networks can be used as a parallel computational model for argumentation and (ii) neural networks can be used to combine argumentation, quantitative reasoning and statistical learning. At the same time, non-standard logic models of argumentation started to emerge. In this paper, we propose a connectionist cognitive model of argumentation that accounts for both standard and non-standard forms of argumentation. The model is shown to be an adequate framework for dealing with standard and non-standard argumentation, including joint-attacks, argument support, ordered attacks, disjunctive attacks, metalevel attacks, self-defeating attacks, argument accrual and uncertainty. We show that the neural cognitive approach offers an adequate way of modelling all of these different aspects of argumentation. We have applied the framework to the modelling of a public prosecution charging decision as part of a real legal decision making case study containing many of the above aspects of argumentation. The results show that the model can be a useful tool in the analysis of legal decision making, including the analysis of what-if questions and the analysis of alternative conclusions. The approach opens up two new perspectives in the short-term: the use of neural networks for computing prevailing arguments efficiently through the propagation in parallel of neuronal activations, and the use of the same networks to evolve the structure of the argumentation network through learning (e.g. to learn the strength of arguments from data).

It is based on the category of small categories, with cloven Grothendieck bifibrations used to model dependent types. The identity type is modelled by a path functor that seems to have independent interest from the point of view of homotopy theory. We briefly describe this modelʼs strengths and limitations.

  • Relational semantics for full linear logic
    • Abstract: Publication date: Available online 7 August 2013
      Source:Journal of Applied Logic
      Author(s): Dion Coumans , Mai Gehrke , Lorijn van Rooijen
      Relational semantics, given by Kripke frames, play an essential role in the study of modal and intuitionistic logic. In [4] it is shown that the theory of relational semantics is also available in the more general setting of substructural logic, at least in an algebraic guise. Building on these ideas, in [5] a type of frames is described which generalise Kripke frames and provide semantics for substructural logics in a purely relational form. In this paper we study full linear logic from an algebraic point of view. The main additional hurdle is the exponential. We analyse this operation algebraically and use canonical extensions to obtain relational semantics. Thus, we extend the work in [4,5] and use their approach to obtain relational semantics for full linear logic. Hereby we illustrate the strength of using canonical extension to retrieve relational semantics: it allows a modular and uniform treatment of additional operations and axioms. Traditionally, so-called phase semantics are used as models for (provability in) linear logic [7]. These have the drawback that, contrary to our approach, they do not allow a modular treatment of additional axioms. However, the two approaches are related, as we will explain.

      This paper is largely a review of known results about various aspects of geometric logic. Following Grothendieckʼs view of toposes as generalized spaces, one can take geometric morphisms as generalized continuous maps. The constructivist constraints of geometric logic guarantee the continuity of maps constructed, and can do so from two different points of view: for maps as point transformers and maps as bundles.
