Questions and Answers about the AI Microelectronics Laboratory Dr. Michael A. Covington Last updated 1999 June 21 General information Where is the laboratory? In the Artificial Intelligence Center, Room 111, Boyd GSRC, on the University of Georgia campus. Specifically, the laboratory is room 117. What will I see if I go there? As of June 21, activity is just beginning. We have a working speech synthesizer, an oscilloscope, and some basic electronic breadboarding tools. We're still waiting for two Pentium PCs, a universal device programmer, and the removal of some obsolete equipment presently in the room. Let me rephrase that. How is the lab going to be outfitted? Initially, there is going to be an electronics workbench, a PC for microelectronics projects, a Sun workstation, and a PC for speech synthesis and recognition projects. The lab also contains a desk and PC for the lab technicians who support all three AI laboratories. Who's paying for it? Two computers were funded by the College of Arts and Sciences. Hewlett-Packard has donated about $5500 worth of equipment, and other electronics companies have expressed an interest in helping us. Why isn't it in the Department of Electrical Engineering?

They are characterised by a number of properties ; non-classical logics are those that lack one or more of these properties, which are: Law of the excluded middle and Double negative elimination Law of noncontradiction Monotonicity of entailment and Idempotency of entailment Commutativity of conjunction De Morgan duality : every logical operator is dual to another. Classical logic is bivalent , i.e. it uses only Boolean-valued functions . And while not entailed by the preceding conditions, contemporary discussions of classical logic normally only include propositional and first-order logics. edit Examples of classical logics Aristotle 's Organon introduces his theory of syllogisms , which is a logic with a restricted form of judgments: assertions take one of four forms, All Ps are Q Some Ps are Q No Ps are Q , and Some Ps are not Q . These judgments find themselves if two pairs of two dual operators, and each operator is the negation of another, relationships that Aristotle summarised with his

Students will be introduced to some of the more important non-classical logics such as modal, temporal, intuitionistic, paraconsistent, relevant and substructural logics. Details of the semantics and proof-theories of these logics will be considered, as well as the philosophical rationales for the logics. On completion of the subject, students should have a good understanding of the technical details of the logics covered, and of philosophical debates surrounding these logics.

19. MOLOG Once the user has chosen the set of inference rules to be used (and thus a nonclassical logic), MOLOG works just as a Prolog interpreter given a database http://www.irit.fr/ACTIVITES/EQ_ALG/Herzig/molog.html

LILaC Topic: MOLOG - a tool for non-classical logic programming Participants: Luis Fariñas del Cerro Andreas Herzig C-Prolog versions in 1986 and 1988, adapted to other Prolog interpreters by J.-F. Bosc in 1992. The principles of an abstract machine have been elaborated by M. Bricard in 1987. This work has been continued by J. Garmendia Aguirre and J.-M. Alliot and has led the latter to implementations in ADA and C in 1991. MOLOG is a general inference machine for building a large class of meta-interpreters. It is in particular suitable for implementing extensions of Prolog with non-classical logics such as logics of knowledge, belief, time, action, uncertainty, etc. MOLOG handles Prolog clauses (with conjunctions and implications ) qualified by modal operators , such as pos:it_rains (it is possible that it rains), or knows(a):pos:it_rains (agent a knows that it is possible that it rains). The user has the possibility to define his modal operators. The language can be multi-modal (i.e., contain several modal operators at the same time). Classical resolution is extended with modal resolution rules that define the operations that can be performed on the modal operators. These rules depend on the modal logic. The MOLOG user can either use an already existing set of resolution rules, or create his own set of rules.

27. Outlines Of A Non-classical Logic For The Approach Of Fuzziness Since the classical logic is not apt to deal with indeterminacy, a new approach of the latter will be a nonclassical one that may be called an aoristic http://www.ici.ro/ici/revista/sic1999_4/art06.html

Outlines Of A Non-classical Logic for the Approach Of Fuzziness Alexandru Giuculescu 7-9 Vasile Conta str., 70139 Bucharest ROMANIA The concept of fuzziness may be approached more efficiently if it is considered as a fact of indeterminacy , that also covers many other concepts known under several labels like ambiguity, equivocacy, undecidability, uncertainty, vagueness, or crisis, chaos, disorder, entropy, etc. In this paper, for clarity’s sake, semantical aspects will be, as much as possible, separated from the logical ones on the reason that the lack of verbal exactness may be remedied by avoiding, or replacing vague or ambiguous terms and expressions or/and stressing the intended meaning by redundancy. Semantic indeterminacy is usually provisional and it is to be eliminated, by convenient operations, even in mathematics. The problem of indeterminacy is for logicians as old as that of determination, but the latter got priority since the former was considered as lying without the scope of science. However Aristotle dealt with it in " De Interpretatione field-path the first member exists alone even without a path, while the second member may be thought as a mere possibility and cannot be imagined in the absence of the field. From this example one may conclude that indeterminacy possesses a structure of possible components which can eventually change even the character of indeterminacy, but they conserve it as long as these components remain mere possibilities with equal chances to turn true. The metaphor of the pair field-path may also serve to reveal the ontological roots of

28. HYLE 5-1 (1999): Atomism And The Reasoning By A Non-Classical Logic Of course, we do not claim that people deliberately argued by means of a nonclassical logic before it was recognized and properly formalized. http://www.hyle.org/journal/issues/5/drago.htm

HYLE – International Journal for Philosophy of Chemistry, Vol. 5 (1999), No. 1 , pp. 43-55 Atomism and the Reasoning by a Non-Classical Logic Abstract: A A does not apply. Recent studies recognized in the failure of this logical law the borderline between classical and non-classical logics. Original writings by classical chemists dealing with the problem of atomism are particularly characterized by the occurrences of DNSs. An historical case, Avogadro’s contribution to atomism ( i.e. the well-known hypothesis about the constitution of gases), is here analyzed in such terms. It turns out that, in order to support his ideas, Avogadro suggested several ad absurdum proofs, indeed a way of reasoning typically linked to the use of DNSs. Keywords: atomism, logic, Avogadro Introduction A A (read: ‘not-not- A implies A’ , where A is any statement), which holds true for classical logic, whilst it fails for non-classical ones.[ In other words, the basic difference between classical and non-classical logics may be confined to the law of double negation: if classical logic applies, a double negated sentence implies its related positive, otherwise we have what we call a DNS, i.e.

The Normal and the Abnormal: Historical and cultural perspectives on norms and deviations SSHM Research Symposium, CHSTM and Wellcome Unit, Manchester 10-11 July 2002. ABSTRACTS Andrew ABERDEIN, Deviance, logic and deviant logic I will explore whether challenges to cultural norms can reach as far as the norms of logic. In particular, shall seek to determine the influence of pluralism in formal logic on this debate. I shall discuss three notable examples of discourses in which attempts have been made to link deviant logic with social deviancy: * Psychoanalysis. Some twentieth-century psychoanalysts have made significant use of formal logic in the articulation of their theories (Matte Blanco, Bion). This step makes a link from deviant behaviour to deviant logic easy to draw. * Feminism. Feminist critics of formal logic have sought to argue that the norms of (classical) logic are implicitly gendered, betraying a masculine bias which should be transgressed. Some of them wish to overthrow formal logic entirely (Nye), but others have argued that the adoption of a suitable non-classical logic would provide a progressive resolution (Plumwood).

Creating SATURATE Input Files From (Non-)Classical Logic Formulae Introduction Getting Started Usage Theory ... Examples Introduction The purpose of this program is twofold: First, it provides us with a means to translate modal and intuitionistic formulae into classical first-order predicate logic, and, second, it generates the clause normal form of arbitrary first-order predicate logic formulae. It is meant to serve as a preprocessor for the SATURATE theorem prover. Getting started "translate" defines some logical operators as listed in the following table. Operator Semantics Associativity and logical and yfx or logical or yfx equivalent xfx implies xfy not fy dia modal diamond fy box modal box fy internal function yfx internal function xfx Moreover, the predicates "logic_list/1", "translate/0", "translate/6", and "make_file/4", are provided (see explanation below). Usage The predicate logic_list(X) shows which logics are currently available. The value of X might change in different versions of this translator. Quite typical is the following: I.e. this version allows us to create SATURATE files from (first-order) formulae of classical predicate logic, intuitionistic logic, and the modal logics K, KD, KD45, S4, S4.2, and S5 (this list might be extended, however).

Journals Journal of Symbolic Logic Bulletin of Symbolic Logic Review of Symbolic Logic Journal of Philosophical Logic ASL Reviews Subscriptions ... Back Volumes The Bulletin of Symbolic Logic was established in 1995 by the Association for Symbolic Logic to provide a journal of high standards that would be both accessible and of interest to as wide an audience as possible. It is designed to cover all areas within the purview of the ASL: mathematical logic and its applications, philosophical and non-classical logic and its applications, history and philosophy of logic, and philosophy and methodology of mathematics. The Bulletin of Symbolic Logic primarily publishes two types of papers: Articles present topics of broad interest in a way that is accessible to a large audience. They can be purely expository, survey, or historical articles or they may contain, in addition, new ideas or results or new approaches to old ones. Communications should be announcements of important new results and ideas in any aspect of logic; they may be short papers in their final form or preliminary announcements (extended abstracts, position papers) of longer, full papers that will be published elsewhere. In any case, they should include, in addition to a description of the new results or ideas, enough history, background, and explanation to make the significance of the work apparent to a wide audience.

45. Pathways To Philosophical Logic And The Philosophy Of Logic The subject of nonclassical logic is now far too big to permit the writing of a comprehensive textbook, so I have had to place some restrictions on what is http://www.formalontology.it/pathways_logic.htm

Home Site Map Pathways to Western Philosophy Philosophical Logic and Philosophy of Logic INTRODUCTORY READINGS Priest Graham. Logic: a very short introduction . Oxford: Oxford University Press 2000. From the Preface: "This book is an introduction to logic, as contemporary logicians now understand the subject. It does not attempt to be a textbook, however. There are numerous such books currently available. The point of this one is to explore the roots of logic, which sink deep into philosophy. Some format logic will be explained along the way. In each of the main chapters, I start by taking up some particular philosophical problem or logical puzzle. I then explain one approach to it. Often this is a fairly standard one; but in some of the areas there is no standard answer: logicians still disagree. In such cases, I have just chosen one that is interesting. Nearly all the approaches, whether standard or not, may be challenged. I finish each chapter with some problems for the approach that I have explained. Sometimes these problems are standard; sometimes they are not. Sometimes they may have easy answers; sometimes they may not. The aim is to challenge you to figure out what you make of the matter. Modern logic is a highly mathematical subject. I have tried to write the material in such a way as to avoid nearly all mathematics. The most that is required is a little high-school algebra in the last few chapters. It is true that you will need the determination to master some symbolism that may be new to you; but this is a lot less than is required to have a basic grasp of any new language. And the perspicuity that the symbolism gives to difficult questions makes any trouble one may have in mastering it well worth it. One warning, though: reading a book on logic or philosophy is not like reading a novel. There will be times when you will have to read slowly and carefully. Sometimes you may have to stop and think about things; and you should be prepared to go back and reread a paragraph if necessary.

46. Abstracts Of Michael's Other Stuff We argue that both classical logic and nonclassical derivatives, though different in the details, are based on common grounds. This insight gives rise to http://web.inf.tu-dresden.de/~mit/publications/misc/ordered-abstracts.html

Challenges for Action Theories: Solving the Ramification and Qualification Problem Michael Thielscher FILES: LNAI00.* Logic has been heralded as the basis for the next generation of computer systems. While logic and formal methods are indeed gaining grounds in many areas of computer science and artificial intelligence the expected revolution and breakthrough has not happened as yet. Notwithstanding the object oriented paradigm programming as well as processor design is still done in an imperative way which has far-reaching consequences for the quality of software and engineering products. A logic based approach to the design of computing systems would, undoubtedly, offer many advantages over the imperative paradigm most commonly applied so far for programming and hardware design and, consequently, logic, again and again, has been heralded as the basis for the next generation of computer systems. While logic and formal methods are indeed gaining ground in many areas of computer science and artificial intelligence, the expected revolution has not yet happened. In the eighties is was beginning to dawn on the logic community that for most applications logic, as used then, might lack a vital ingredience, which, on the other hand, is inherent in imperative languages and which no one wants to miss: a simple and natural way of describing action and change without facing inherent problems. In AI, these problems centered around what is called the frame problem. Fortunately, the frame problem has finally been solved in such a way that the drawback is disappearing.

Gabbay, FRSC Publications List th November 2004 Published or Accepted for Publication (Books are indicated in Larger Bold Italic font) Investigations in Modal and Tense Logics with Applications Synthese volume 92, D. Reidel, 1976. 321 pp, The main research thrust of this monograph is to present comprehensive methods for proving decidability and undecidability for modal and temporal systems. General theorems are proved on the one hand and new classification and semantical characterisations are given to many logics in order to show that they satisfy these general theorems. Counter examples are constructed to show the limitations of various methods. The book also lays the mathematical and conceptual foundations for non—classical logics. Semantical Investigations in Heyting's Intuitionistic Logic Synthese volume 148. D. Reidel, 1981. 300 pp, This monograph uses semantical methods to study intuitionistic and various neighbouring systems. It develops their mathematical model theory and finite model property and studies their proof theory and interpolation properties. It further applies the methods of book 1, to obtain decidability and undecidability results for intuitionistic algebraic theories. Both research monographs are partially based on, and extend, some of the related research papers.
