Ontic : a knowledge representation system for mathematics by
David A McAllester(
Book
)
9 editions published between 1987 and 1989 in English and Undetermined and held by 254 WorldCat member libraries worldwide
Ontic is an interactive system for developing and verifying mathematics. Ontic's verification mechanism is capable of automatically finding and applying information from a library containing hundreds of mathematical facts. Starting with only the axioms of ZermeloFraenkel set theory, the Ontic system has been used to build a data base of definitions and lemmas leading to a proof of the Stone representation theorem for Boolean lattices. The Ontic system has been used to explore issues in knowledge representation, automated deduction, and the automatic use of large data bases. Keywords: Cognitive models; Inference; Compilers; Programming languages; Stone representation theorem; Automated reasoning

An outlook on truth maintenance by
David A McAllester(
Book
)
3 editions published in 1980 in English and held by 7 WorldCat member libraries worldwide
Truth maintenance systems (TMS) have been used in several recent problemsolving systems to record justifications for deduced assertions, to track down the assumptions which underlie contradictions when they arise, and to incrementally modify assertional data structures when assumptions are retracted. This report describes a TMS algorithm that is substantially different from previous systems. This algorithm performs deduction in traditional propositional logic in such a way that the premise set from which deduction is being done can be easily manipulated. A novel approach is also taken to the role of a TMS in larger deductive systems. In this approach the TMS performs all propositional deduction in a uniform manner while the larger system is responsible for controlling the instantiation of universally quantified formulae and axiom schemas

A three valued truth maintenance system by
David A McAllester(
Book
)
3 editions published in 1978 in English and held by 7 WorldCat member libraries worldwide
Truth maintenace systems have been used in recently developed problem solving systems. A truth maintenance system (TMS) is designed to be used by deductive systems to maintain the logical relations among the beliefs which those systems manipulate. These relations are used to incrementally modify the belief structure when premises are changed, giving a more flexible context mechanism than has been present in earlier artificial intelligence systems. The relations among beliefs can also be used to directly trace the source of contradictions or failures, resulting in far more efficient backtracking. In this paper a new approach is taken to truth maintenance algorithms. Each belief, or proposition, can be in any one of three truth states, true, false, or unknown. The relations among propositions are represented in disjunctive classes. By representing an implication in a clause the same algorithm that is used to deduce its consequent can be used to deduce the negation of antecedents that would lead to contradictions. A simple approach is also taken to the handling of assumptions and back tracking which does not involve the nonmonotonic dependency structures present in other truth maintenance systems. (Author)

The use of equality in deduction and knowledge representation by
David A McAllester(
Book
)
2 editions published in 1980 in English and held by 5 WorldCat member libraries worldwide
This report describes a system which maintains canonical expressions for designators under a set of equalities. Substitution is used to maintain all knowledge in terms of these canonical expressions. A partial order on designators, termed the bettername relation, is used in the choice of canonical expressions. It is shown that with an appropriate bettername relation an important engineering reasoning technique, propagation of constraints, can be implemented as a special case of this substitution process. Special purpose algebraic simplification procedures are embedded such that they interact effectively with the equality system. An electrical circuit analysis system is developed which relies upon constraint propagation and algebraic simplification as primary reasoning techniques. The reasoning is guided by a bettername relation in which referentially transparent terms are preferred to referentially opaque ones. Multiple description of subcircuits are shown to interact strongly with the reasoning mechanisms

Natural language based inference procedures applied to Schubert's steamroller by Robert Givan(
Book
)
2 editions published in 1991 in English and held by 4 WorldCat member libraries worldwide
Abstract: "We have previously argued that the syntactic structure of natural language can be exploited to construct powerful polynomial time inference procedures. This paper supports the earlier arguments by demonstrating that a natural language based polynomial time procedure can solve Schubert's steamroller in a single step."

Boolean classes by
David A McAllester(
Book
)
2 editions published in 1986 in English and held by 4 WorldCat member libraries worldwide
Objectoriented programming languages all involve the notions of class and object. The authors extend the notion of class so that any Boolean combination of classes is also a class. Boolean classes allow greater precision and conciseness in naming the class of objects governed by a particular method. A class can be viewed as a predicate which is either true or false of any given object. U nlike predicates however classes have an inheritance hierarchy which is known at compile time. Boolean classes extend the notion of class, making classes more like predicates, while preserving the compile time computable inheritance hierarchy. (Author)

Lifting transformations by

2 editions published in 1991 in English and held by 4 WorldCat member libraries worldwide
Abstract: "Lifting is a well known technique in resolution theorem proving, logic programming, and term rewriting. In this paper we formulate lifting as an efficiencymotivated program transformation applicable to a wide variety of nondeterministic procedures. This formulation allows the immediate lifting of complex procedures, such as the DavisPutnam algorithm, which are otherwise difficult to lift. We treat both classical lifting, which is based on unification, and various closely related program transformations which we also call lifting transformations. These nonclassical lifting transformations are closely related to constraint techniques in logic programming, resolution, and term rewriting. Formulating these techniques as transformations on nondeterministic programs expands the range of procedures to which the techniques can be easily applied."

Automatic recognition of tractability in inference relations by
David A McAllester(
Book
)
2 editions published in 1990 in English and held by 3 WorldCat member libraries worldwide
A procedure is given for recognizing sets of inference rules that generate polynomial time decidable inference relations. The procedure can automatically recognize the tractability of the inference rules underlying congruence closure. The recognition of tractability for that particular rule set constitutes mechanical verification of a theorem originally proved independently by Kozen and Shostak. The procedure is algorithmic, rather than heuristic, and the class of automatically recognizable tractable rule sets can be precisely characterized. A series of examples of rule sets whose tractability is nontrival, yet machine recognizable, is also given. The technical framework developed here is reviewed as a first step toward a general theory of tractable inference relations. Keywords: Statistical inference, Machine inference, Theorem proving, Automated reasoning, Polynomial time decidability, Inference rules, Proof systems, Mechanical verification. (KR)

Reasoning Utility Package User's Manual. Version One by
David A McAllester(
Book
)
3 editions published in 1982 in English and held by 3 WorldCat member libraries worldwide
RUP (Reasoning Utility Package) is a collection of procedures for performing various computations relevant to automated reasoning. RUP contains a truth maintenance system (TMS) which can be used to perform simple propositional deduction (unit clause resolution), to record justifications, to track down underlying assumptions, and to perform incremental modifications when premises are changed. This TMS can be used with an automatic premise controller which automatically retracts 'assumptions' before 'solid facts' when contradictions arise and searches for the most solid proof of an assertion. RUP also contains a procedure for efficiently computing all the relevant consequences of any set of equalities between ground terms. A related utility computes 'substitution simplifications' of terms under an arbitrary set of unquantified equalities and a user defined simplicity order. RUP also contains demon writing macros which allow one to write PLANNER like demons that trigger on various types of events in the data base. Finally there is a utility for reasoning about partial orders and arbitrary transitive relations. In writing all of these utilities an attempt has been made to provide a maximally flexible environment for automated reasoning. (Author)

Grammar rewriting by

2 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide
Although the procedure is primarily intended for use in nonconfluent theories, it also provides a new kind of confluence that can be used to give canonical rewriting systems for theories that are difficult to handle in other ways. For example, under grammar rewriting there is a finite canonical rewrite system for idempotent semigroups, a theory which has been shown not to have any finite canonical system under traditional notions of rewriting."

Taxonomic syntax for first order inference by
David A McAllester(
Book
)
3 editions published in 1989 in English and held by 3 WorldCat member libraries worldwide
Most knowledge representation languages are based on classes and taxonomic relationships between classes. Taxonomic hierarchies without defaults or exceptions are semantically equivalent to a collection of formulas in first order predicate calculus. Although designers of knowledge representation languages often express an intuitive feeling that there must be some advantage to representing facts as taxonomic relationships rather than first order formulas, there are few, if any, technical results supporting this intuition. We attempt to remedy this situation by presenting a taxonomic syntax for first order predicate calculus and a series of theorems that support the claim that taxonomic syntax is superior to classical syntax. Keywords: Artificial intelligence, Theorem proving, Inference, Automated reasoning

Nonexpressibility of fairness and signaling by
David A McAllester(
Book
)
2 editions published in 1989 in English and held by 3 WorldCat member libraries worldwide
Abstract: "In this paper we establish new expressiveness results for indeterminate dataflow primitives. We consider choice primitives with three differing fairness assumptions and show that they are strictly inequivalent in expressive power. We also show that the ability to announce choices enhances the expressive power of two of the primitives. These results are proved using a very crude semantics and thus apply in any reasonable theory of process equivalence."

Observations on cognitive judgments by

Abstract: "It is obvious to anyone familiar with the rules of the game of chess that a king on an empty board can reach every square. It is true, but not obvious, that a knight can reach every square. Why is the first fact obvious but the second fact not? This paper presents an analytic theory of a class of obviousness judgments of this type. Whether or not the specifics of this analysis are correct, it seems that the study of obviousness judgments can be used to construct integrated theories of linguistics, knowledge representation, and inference."
