Method Detail

isSolverTerminated

public boolean isSolverTerminated(SolverScope<Solution_> 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 all the Terminations are terminated.

isPhaseTerminated

public boolean isPhaseTerminated(AbstractPhaseScope<Solution_> phaseScope)

Description copied from interface: Termination

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

Parameters:

phaseScope - never null

Returns:

true if all the Terminations are terminated.

calculateSolverTimeGradient

public double calculateSolverTimeGradient(SolverScope<Solution_> solverScope)

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

Parameters:

solverScope - never null

Returns:

the minimum timeGradient of the Terminations.

calculatePhaseTimeGradient

public double calculatePhaseTimeGradient(AbstractPhaseScope<Solution_> phaseScope)

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

Parameters:

phaseScope - never null

Returns:

the minimum timeGradient of the Terminations.

createChildThreadTermination

public AndCompositeTermination<Solution_> createChildThreadTermination(SolverScope<Solution_> solverScope,
                                                                       ChildThreadType childThreadType)

Description copied from interface: Termination

Create a Termination for a child Thread of the Solver.

Specified by:

createChildThreadTermination in interface Termination<Solution_>

Overrides:

createChildThreadTermination in class AbstractTermination<Solution_>

Parameters:

solverScope - never null

childThreadType - never null

Returns:

not null

toString

public String toString()

Overrides:

toString in class Object
