Abstract

As the SAT competition has shown, frequent restarts improve the speed of SAT solvers tremendously, particularly on satisfiable industrial instances. This paper presents a novel adaptive technique that measures the agility of the search process dynamically, which in turn is used to control the restart frequency. Experiments demonstrate, that this new dynamic restart strategy improves speed of our SAT solver PicoSAT on crafted instances considerably and on industrial instances slightly.
