Method Detail

isSolverTerminated

public boolean isSolverTerminated(DefaultSolverScope solverScope)

Description copied from interface: Termination

Called by the Solver after every phase to determine if the search should stop.

Parameters:

solverScope - never null

Returns:

true if any of the Termination is terminated.

isPhaseTerminated

public boolean isPhaseTerminated(AbstractSolverPhaseScope phaseScope)

Description copied from interface: Termination

Called by the SolverPhase after every step and every move to determine if the search should stop.

Parameters:

phaseScope - never null

Returns:

true if any of the Termination is terminated.

calculateSolverTimeGradient

public double calculateSolverTimeGradient(DefaultSolverScope solverScope)

Calculates the minimum timeGradient of all Terminations. Not supported timeGradients (-1.0) are ignored.

Parameters:

solverScope - never null

Returns:

the maximum timeGradient of the Terminations.

calculatePhaseTimeGradient

public double calculatePhaseTimeGradient(AbstractSolverPhaseScope phaseScope)

Calculates the minimum timeGradient of all Terminations. Not supported timeGradients (-1.0) are ignored.

Parameters:

phaseScope - never null

Returns:

the maximum timeGradient of the Terminations.
