Lazy Thinking Algorithm Synthesis in Gröbner Bases Theory

Adrian Craciun

Research Institute for Symbolic Computation (RISC). PhD Thesis. 2008. [pdf]
[bib]
@phdthesis{RISC3425,
author = {Adrian Craciun},
title = {{Lazy Thinking Algorithm Synthesis in Gröbner Bases Theory}},
language = {english},
abstract = {This thesis is concerned with the implementation of the “lazy thinking” synthesis methodin the frame of the mathematical assistant system Theorema and its application to thesynthesis of algorithms in the theory of Gröbner bases. The “lazy thinking” method, proposed by Bruno Buchberger, the first advisor of thisthesis, is part of his model of systematic theory exploration based on knowledge schemes.Essentially, lazy thinking is a deductive, scheme-based synthesis method: a proof of thecorrectness of an algorithm (i.e. its specification) using an algorithm scheme and usingcomplete knowledge about the specification is attempted. All definitions and propertiesof concepts involved in the specifications are known. The algorithm scheme is a definitionof the desired algorithm in terms of unknown subalgorithms. The proof is likely to fail,as no information about the unknown subalgorithms is available. Following an analysisof the failing proof, conjectures are generated and added to the knowledge, such that thefailure can be overcome. These conjectures turn out to be specifications for the unknownsubalgorithms. Algorithms that satisfy the generated specifications can then either beretrieved from the knowledge base, or synthesized by lazy thinking in subsequent roundsof exploration.We describe the method of lazy thinking and then describe its implementation in Theo-rema: • the cascade mechanism, that implements the lazy exploration cycles (initiate proof, proof failure analysis, conjecture generation), • failure analysis, and • conjecture generation.We then describe the usage of the cascade mechanism in conjunction with the reasonersavailable in the system. The problem of Gröbner bases represents a nontrivial benchmark for program synthesis.We present how, following an outline proposed by Bruno Buchberger, the lazy thinkingimplementation can be used in this case study. Starting from a critical-pair completionalgorithm scheme, we show how our implementation can be applied successfully to ef-fectively (re)invent the idea of S-polynomials (as outlined by Bruno Buchberger), andcomplete a proof of correctness.},

Multi-Domain Logic and its Applications to SAT

[bib]
@inproceedings{RISC3949,
author = {Tudor Jebelean and Gabor Kusper},
title = {{Multi-Domain Logic and its Applications to SAT}},
booktitle = {{SYNASC 2008}},
language = {English},
abstract = {We describe a new formalism and special proof methods for a novel generalization of propositional logic,which is especially suitable for solving the satisfiability problem (SAT).A Multi--Domain Logic (MDL) formula is quantifier--free and contains only atoms of the form $x \in A$,where $x$ is a variable and $A$ is a constant set.For formulae in conjunctive normal form, we are interested in finding solutions (assignments to variables which satisfy all clauses).Classical propositional logic corresponds to the special case when each set is either $\{\true\}$ or $\{\false\}$.The union of all the sets occurring for a certain variable can be seen as "the domain" of that variable, thus MDL is also a generalization of multi-valued logic, but with different domains for variables.The most distinctive feature is, however, the indication of the sub-domain in each clause.The notions of resolution, subsumption, as well as the basic steps of the DPLL method generalize in an elegant and straightforward way.As a novel MDL specific technique, {\em variable clustering} consists in creating a new variable ranging over the cartesian product of the domains of several "clustered" variables.This allows the transformation of classical SAT problems in MDL problems with less literals, and in which the propagation of information can be performed more efficiently than classical unit propagation.The basic idea of MDL originates from the earlier work of the second author on "hyper-unit" propagation (that is simultaneous propagation of several unit clauses) and on the representation and propagation of "k-literals" (generalized literals containing information on several propositional variables).Preliminary experiments with a prototype Java implementation exhibit speed--ups of up to 30 times.},
