    Logic, Games, and Computation. Spring , Stanford, We - PM, J. Johan van Benthem. Abstract. This course is a tour of current interfaces between logic and game theory. Logical argumentation or model checking can be cast as games between players trying to achieve purposes through optimal strategies. Such 'logic. In the last 20 years many proposals have been made to incorporate non-monotonic reasoning into description logics, ranging from approaches based on default logic and circumscription to those based on preferential semantics. In particular, the non-monotonic description logic ALC+Tmin uses a combination of the preferential semantics with.

Fitting in [8, 9, 10, 12]. In this family, the underlying propositional logics employ finite Heyting algebras for the space of truth. Mathematical Problems from Applied Logic I presents chapters from selected, world renowned, logicians. Important topics of logic are discussed from the point of view of their further development in light of requirements arising from their successful application in areas such as Computer Science and AI .

Abstract. In this paper we provide a semantic characterization of ground logics, a family of nonmonotonic modal logics obtained by means of a variant of the well known Mc Dermott and Doyle fixed point Cited by: 6.

Abstract. We investigate the problem of reasoning in nonmonotonic extensions of first-order logic. In particular, we study reasoning in firstorder MKNF, the modal logic of minimal knowledge and negation as failure introduced by by: 6.

We start by presenting the main concepts of "standard DEL" (as covered e.g. in the book ``Dynamic Epistemic Logic" and in several ESSLLI courses with the same name): multi-agent epistemic Kripke models, public announcements, epistemic event models, product. Dynamic epistemic logic, broadly conceived, is the study of rational social interaction in context, the study, that is, of how agents update their knowledge and change their beliefs on the basis Author: Jan Van Eijck.

from book The age of alternative ing philosophy of logic and mathematics today. Based on the conference on philosophical insights into logic and mathematics, Nancy, France, September. This is an essential book for any student of the subject, written by a master of the field.' Dov Gabbay - King's College London ' this book is the best we can have for now as a great source for the research in the field of logical dynamics of information and interaction.

It can be used as a handbook of DEL as by: In this article, we introduce an epistemic modal operator modelling knowledge over distributive non-associative full Lambek calculus with a negation. Our approach is based on the relational semantics for substructural logics: we interpret the elements of a relational frame as information states consisting of collections of data.

The Gabbay-Makinson rules for cumulative consequence relations are a paradigmatic example of this epistemic approach. Current dynamic epistemic logics for analyzing effects of informational events often become cumbersome and opaque when common knowledge is added for groups of agents.

in social choice theory. Also, in a more abstract sense, preference orderings are used in conditional logic or non-monotonic reasoning as a way of arranging worlds into more.

Non-monotonic logics are used for (among other things) reasoning with information of different quality. For instance, to take the most common example, the sentence “birds fly” of common sense reasoning does not mean that all birds fly, with “all” the classical quantifier, but that the majority of birds fly, the interesting ones fly, or.

We will focus especially on modal logic and non-classical logics, considering the application of modal logic to the analysis of conditionals and propositional attitudes and issues that emerge in the interaction between modal logic and quantification, and exploring non-classical logics such as intuitionism, relevance logic, and many-valued Occupation: Professor.

Many non-monotonic systems with fixed-point or preferential semantics fit this view. However, sometimes the rules govern a process of argument (the last view on this list), so that they cannot be re-compiled into a set of deductive rules lest they lose their force in situations with incomplete knowledge or incomplete derivation of preconditions.

Goncharov, and Michael Zakharyaschev, editors. Full Description: "This book celebrates and expands on J. Michael Dunn’s work on informational interpretations of logic. Dunn, in his Ph.D. thesis (), introduced a semantics for first-degree entailments utilizing the idea that a sentence can provide positive or negative information about a topic, possibly supplying both or neither.

The crucial final equivalence states which conditional beliefs agents form after soft upgrade. (Here a51 is the earlier epistemic existential modality 〈K〉.) This formula may look daunting, but try to read the principles of some non-monotonic default logics existing today.

And there is a reward. Common knowledge (logic) General knowledge is a special kind of knowledge for the agent group. There is common knowledge of p in a group of agents g when all agents In G know P, they all know that they know p, they all know they all know that they know P, And so on to infinity.

Full Description: ""Equations play a vital role in many fields of mathematics, computer science, and artificial intelligence. Therefore, many proposals have been made to integrate equational, functional, and logic programming.

This book presents the foundations of equational logic programming. The book Knowledge in Flux: Modeling the Dynamics of Epistemic States from With this volume, Peter Gärdenfors initiated the disciplines of dynamic semantics, epistemic logics and pragmatic information theory.

According to this approach, the meaning of a proposition is. Naming and identity in epistemic logics, I: The propositional case. Adam and Joseph Y. Halpern. Modal epistemic logics for many agents often assume a fixed one-to-one correspondence between agents and the names for agents that occur in the language.

This assumption restricts the applicability of any logic because it prohibits, for. The general view: fixed-point logics for game trees.

We are now in the realm of a well-known logic of computation, viz. first-order fixed-point logic LFP (FO).

The above analysis really tells us: Theorem The BI relation is definable as a greatest-fixed-point formula in the logic LFP (FO).
