public class LingelingSolver
extends SatSolver

A wrapper for the Lingeling SAT solver (tested with Lingeling version ats1 ce8c04fc97ef07cf279c0c5dcbbc7c5d9904230a). See http://fmv.jku.at/lingeling/. NOTE: so far no further configuration possible.

The binary location of Lingeling.

Constructor Detail

LingelingSolver

public LingelingSolver(java.lang.String binaryLocation)

Creates a new solver based on the Lingeling executable given as a parameter.

Parameters:

binaryLocation - the path to the executable.

Method Detail

getWitness

public Interpretation getWitness(java.util.Collection<PropositionalFormula> formulas)

Description copied from class: SatSolver

If the collection of formulas is consistent this method returns some model of it or, if it is inconsistent, null.

Specified by:

getWitness in interface ConsistencyWitnessProvider<PropositionalFormula>

Specified by:

getWitness in class SatSolver

Returns:

some model of the formulas or null.

isSatisfiable

public boolean isSatisfiable(java.util.Collection<PropositionalFormula> formulas)

Description copied from class: SatSolver

Checks whether the given set of formulas is satisfiable.

Specified by:

isSatisfiable in class SatSolver

Parameters:

formulas - a set of formulas.

Returns:

"true" if the set is consistent.
