Field Detail

### startingTemperature

    protected Score startingTemperature

### partsLength

    protected int partsLength

### startingTemperatureParts

    protected double[] startingTemperatureParts

### temperatureParts

    protected double[] temperatureParts

### temperatureMinimum

    protected double temperatureMinimum

Constructor Detail

### SimulatedAnnealingAcceptor

    public SimulatedAnnealingAcceptor()

Method Detail

### setStartingTemperature

    public void setStartingTemperature(Score startingTemperature)

### phaseStarted

    public void phaseStarted(LocalSearchSolverPhaseScope localSearchSolverPhaseScope)

  Specified by:
    `phaseStarted` in interface `LocalSearchSolverPhaseLifecycleListener`
  Overrides:
    `phaseStarted` in class `LocalSearchSolverPhaseLifecycleListenerAdapter`

### calculateAcceptChance

    public double calculateAcceptChance(MoveScope moveScope)

  Description copied from interface: `Acceptor`
  TODO the use for an acceptChance between 0.0 and 1.0 is unproven. A boolean instead of a double is sufficient?

  Parameters:
    `moveScope` - not null
  Returns:
    never negative; if rejected 0.0; if accepted higher than 0.0 (usually 1.0)

### stepTaken

    public void stepTaken(LocalSearchStepScope localSearchStepScope)

  Specified by:
    `stepTaken` in interface `LocalSearchSolverPhaseLifecycleListener`
  Overrides:
    `stepTaken` in class `LocalSearchSolverPhaseLifecycleListenerAdapter`
