CLASP(1)						      General Commands Manual							  CLASP(1)

NAME

       clasp - a conflict-driven nogood learning answer set solver

SYNOPSIS

       clasp [number][options]

DESCRIPTION

       This manual page documents briefly the clasp command.

       clasp  is  an answer set solver for (extended) normal logic programs. It combines the high-level modeling capacities of answer set program-
       ming (ASP) with state-of-the-art techniques from the area of Boolean constraint solving. The primary clasp algorithm  relies  on  conflict-
       driven nogood learning, a technique that proved very successful for satisfiability checking (SAT). Unlike other learning ASP solvers, clasp
       does not rely on legacy software, such as a SAT solver or any other existing ASP solver. Rather, clasp has  been  genuinely  developed  for
       answer  set  solving  based  on	conflict-driven nogood learning. clasp can be applied as an ASP solver (on LPARSE output format), as a SAT
       solver (on simplified DIMACS/CNF format), or as a PB solver (on OPB format).

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.	For a complete description, see <http://www.cs.uni-potsdam.de/clasp/>.

       -h, --help
	      Show summary of options.

       -v, --version
	      Show version of program.

       clasp was written by Benjamin Kaufmann <kaufmann@cs.uni-potsdam.de>.
