Constructor Details

OctaveSqpSolver

public OctaveSqpSolver()

Default constructor. If "octave" is not in the PATH, it must be set using the static method "setPathToOctave"

Method Details

setPathToOctave

public static void setPathToOctave(String pathToOctave)

Set path

Parameters:

pathToOctave - path

solve

public Map<Variable,Term> solve(GeneralConstraintSatisfactionProblem problem)
                         throws GeneralMathException

Description copied from class: Solver

Computes a solution to the given constraint satisfaction or optimization problem, i.e. a mapping from variables of the problem to terms.

Specified by:

solve in class Solver

Parameters:

problem - the actual problem

Returns:

a mapping from variables of the problem to terms.

Throws:

GeneralMathException - if something went wrong.

isInstalled

public static boolean isInstalled()
                           throws UnsupportedOperationException

Return if solver is installed

Returns:

if solver is installed

Throws:

UnsupportedOperationException - UnsupportedOperationException
