Description. A SAT solver takes a Boolean expression and finds out if the variables can be replaced by true or false so that the formula evaluates to true. SAT is a problem that belongs in the NP-complete class of problems and was in fact the first ever problem proven to belong to that class. this approach is applicable in the case of massively parallel SAT solving. Our solver is intended to run on clusters with thousands of processors, hence the name HordeSat. HordeSat is a fully distributed portfolio-based SAT solver with a modular design that allows it to use any SAT solver that implements a given interface.
