A timeGradient is a relative estimate of how long the search will continue.

isPhaseTerminated(AbstractPhaseScope phaseScope)
Called by the
Phase after every step and every move 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
