Class LSBBParam

java.lang.Object

localsolverblackbox.LSBBParam

public class LSBBParam
extends java.lang.Object

Solving parameters. This class contains some methods allowing you to parameterize the resolution of the model. For the sake of simplicity, only a few parameters are actually offered to tune the search.

Method Detail

getLocalSolverBlackBox

public LocalSolverBlackBox getLocalSolverBlackBox()

Returns the LocalSolverBlackBox object associated to these parameters.

Returns:

LocalSolverBlackBox object.

setSeed

public void setSeed(int seed)

Sets the seed of the pseudo-random number generator used by the solver. The seed must be a positive integer. The default seed is set to 0. Only allowed in state LSBBState.Stopped.

Parameters:

seed - Seed of the pseudo-random number generator.

getSeed

public int getSeed()

Gets the seed of the pseudo-random number generator used by the solver. Only allowed in states LSBBState.Paused or LSBBState.Stopped.

Returns:

Seed of the pseudo-random number generator.

See Also:

setSeed(int)

setTimeLimit

public void setTimeLimit(int limit)

Sets the time limit in seconds. Note that the "real" time (that is, total time) spent to resolve the model is considered here (and not only the CPU time). The default time limit is set to the largest positive integer on 32 bits, that is 2^31-1 = 2,147,483,647 > 10^9. Only allowed in state LSBBState.Stopped.

Parameters:

limit - Time limit in seconds.

getTimeLimit

public int getTimeLimit()

Gets the time limit in seconds. Only allowed in states LSBBState.Paused or LSBBState.Stopped.

Returns:

Time limit in seconds.

See Also:

setTimeLimit(int)

setEvaluationLimit

public void setEvaluationLimit(int limit)

Sets the maximum number of blackbox evaluations. The default number of evaluations is set to the largest positive integer on 32 bits that is 2^31-1 = 2,147,483,647 > 10^9. Only allowed in state LSBBState.Stopped.

Parameters:

limit - Maximum number of blackbox evaluation.

getEvaluationLimit

public int getEvaluationLimit()

Gets the maximum number of blackbox evalutions. Only allowed in states LSBBState.Paused or LSBBState.Stopped.

Returns:

Evaluation limit.

See Also:

setEvaluationLimit(int)

setObjectiveBound

public void setObjectiveBound(double bound)

Sets the objective bound. If the objective is minimized (resp. maximized), then the optimization of this objective is stopped as soon as this lower (resp. upper) bound is reached. Only allowed in states LSBBState.Stopped.

Parameters:

bound - Objective bound.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
