### PhaseToSolverTerminationBridge

    public PhaseToSolverTerminationBridge(Termination solverTermination)

Method Detail

### solvingStarted

    public void solvingStarted(DefaultSolverScope solverScope)

    `phaseStarted` in interface `SolverPhaseLifecycleListener`
  Overrides:
    `phaseStarted` in class `SolverPhaseLifecycleListenerAdapter`

### stepStarted

    public void stepStarted(AbstractStepScope stepScope)

  Specified by:
    `stepStarted` in interface `SolverPhaseLifecycleListener`
  Overrides:
    `stepStarted` in class `SolverPhaseLifecycleListenerAdapter`

### stepEnded

    public void stepEnded(AbstractStepScope stepScope)

  Specified by:
    `stepEnded` in interface `SolverPhaseLifecycleListener`
  Overrides:
    `stepEnded` in class `SolverPhaseLifecycleListenerAdapter`

### phaseEnded

    public void phaseEnded(AbstractSolverPhaseScope phaseScope)

  Specified by:
    `phaseEnded` in interface `SolverPhaseLifecycleListener`
  Overrides:
    `phaseEnded` in class `SolverPhaseLifecycleListenerAdapter`

    public void solvingEnded(DefaultSolverScope solverScope)

  Specified by:
    `solvingEnded` in interface `SolverLifecycleListener`
  Overrides:
    `solvingEnded` in class `SolverLifecycleListenerAdapter`

### 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 the search should terminate.

### 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 the search should terminate.

### calculateSolverTimeGradient

    public double calculateSolverTimeGradient(DefaultSolverScope solverScope)

  Description copied from interface: `Termination`
  A timeGradient is a relative estimate of how long the search will continue. Clients that use a timeGradient should cache it at the start of a single step because some implementations are not time-stable. If a timeGradient can not be calculated, it should return -1.0. Several implementations (such a `SimulatedAnnealingAcceptor`) require a correctly implemented timeGradient.

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

  Parameters:
    `solverScope` - never null
  Returns:
    timeGradient t for which 0.0 <= t <= 1.0 or -1.0 when it is not supported. At the start of a solver t is 0.0 and at the end t would be 1.0.

### calculatePhaseTimeGradient

    public double calculatePhaseTimeGradient(AbstractSolverPhaseScope phaseScope)

  Description copied from interface: `Termination`
  See `Termination.calculateSolverTimeGradient(DefaultSolverScope)`.

  Parameters:
    `phaseScope` - never null
  Returns:
    timeGradient t for which 0.0 <= t <= 1.0 or -1.0 when it is not supported. At the start of a phase t is 0.0 and at the end t would be 1.0.
