Automated Discovery of Composite SAT Variable
Selection Heuristics
A. Fukunaga. Proceedings of the National Conference on Artificial
Intelligence (AAAI), Seite 641--648. (2002)
Zusammenfassung
Variants of GSAT and Walksat are among the most
successful SAT local search algorithms. We show that
several well-known SAT local search algorithms are the
results of novel combinations of a set of variable
selection primitives. We describe CLASS, an automated
heuristic discovery system which generates new,
effective variable selection heuristic functions using
a simple composition operator. New heuristics
discovered by CLASS are shown to be competitive with
the best Walksat variants, including Novelty and
R-Novelty . We also analyse the local search behaviour
of the learned heuristics using the depth, mobility,
and coverage metrics recently proposed by Schuurmans
and Southey.
