Constructor Detail

QuteSolver

public QuteSolver(java.lang.String binaryLocation,
                  Shell bash)

Constructs a new instance pointing to a specific QuteSolver.

Parameters:

binaryLocation - of the Qute executable on the hard drive

bash - shell to run commands

QuteSolver

public QuteSolver(java.lang.String binaryLocation)

Constructs a new instance pointing to a specific QuteSolver

Parameters:

binaryLocation - of the Qute executable on the hard drive

Method Detail

evaluate

private boolean evaluate(java.io.File file)
                  throws java.lang.Exception

Invokes Qute with the given input file.

Parameters:

file - input file for Qute

Returns:

true if the result is SAT, false if the result is UNSAT

Throws:

java.lang.Exception - if the bash command fails or if Qute produces no interpretable output

isSatisfiable

public boolean isSatisfiable(java.util.Collection<PlFormula> kb)

Description copied from class: QbfSolver

Checks whether the given set of formulas is satisfiable.

Specified by:

isSatisfiable in class QbfSolver

Parameters:

kb - a set of formulas.

Returns:

"true" if the set is consistent.
