      org.sat4j.sat.Lanceur

All Implemented Interfaces:

Serializable

public class Lanceur
extends AbstractLauncher

This class is used to launch the SAT solvers from the command line. It is compliant with the SAT competition (www.satcompetition.org) I/O format. The launcher is to be used as follows:

                [solvername] filename [key=value]*
 

If no solver name is given, then the default solver of the solver factory is used (@see org.sat4j.core.ASolverFactory#defaultSolver()).
