Abstract

En 中文
We present a method we call structure-based preferential bumping,as a low-cost way to exploit formula structure in VSIDS-based SAT solvers.We show that the Glucose SAT solver, when modified with preferential bumpingof certain easily identified structurally important variables,out-performs unmodified Glucose on the industrial formulasfrom recent SAT solver competitions.
