Overview

HySAT-II is a satisfiability checker for Boolean combinations of potentially non-linear arithmetic constraints over real- and integer-valued variables. It is able to search optimal satisfying valuations, i.e. solutions which minimize or maximize the value of an arbitrary variable occuring in the input formula. The main purpose of HySAT-II is bounded model checking of hybrid (discrete-continuous) systems.
