double |
calculateSolverTimeGradient(DefaultSolverScope solverScope)
A timeGradient is a relative estimate of how long the search will continue.
|
boolean |
isPhaseTerminated(AbstractSolverPhaseScope phaseScope)
Called by the
SolverPhase after every step and every move to determine if the search should stop. |
boolean |
isSolverTerminated(DefaultSolverScope solverScope)
Called by the
Solver after every phase to determine if the search should stop. |

A Termination's timeGradient can be requested after they are terminated, so implementations
should be careful not to return a timeGradient above 1.0.solverScope
