Wasp is an ASP solver handling disjunctive logic programs under the stable model semantics. Wasp implements techniques originally introduced for SAT solving combined with optimization methods that have been specifically designed for ASP computation, such as source pointers enhancing unfounded sets computation and efficient techniques for stable model checking.
Wasp takes as input logic programs in the GRINGO format and SAT/MaxSAT formulas in DIMACS format.
In order to compile wasp boost (http://www.boost.org/) and g++-4.6 (or more recent) are required.
If all libraries have been installed just type:
make
and pray!
Other compiling options are also available:
make BUILD=statsenables the usage of statisticsmake BUILD=traceenables the possibility to trace the internal behavior of waspmake BUILD=debugcompiles wasp for debugging
In order to use wasp you need the grounder GRINGO (http://potassco.sourceforge.net/).
If gringo has been downloaded just type:
./gringo filename | ./wasp
