Solving satisfiability in fuzzy logics with evolution strategies
Tim Brys, Yann-Michaël De Hauwere, Martine De Cock, Ann Nowé · 2012
Satisfiability in propositional logic is well researched and many approaches to checking and solving exist. In infinite-valued or fuzzy logics, however, there have only recently been attempts at developing methods for solving satisfiability. In this paper, we propose a new incomplete solver, based on a class of continuous optimization algorithms called evolution strategies. We show experimentally that our method is an important contribution to the state of the art in incomplete fuzzy-SAT solvers.
