java.lang.Object
org.drools.planner.core.localsearch.decider.acceptor.AbstractAcceptor
org.drools.planner.core.localsearch.decider.acceptor.simulatedannealing.LegacySimulatedAnnealingAcceptor
- All Implemented Interfaces:
- Acceptor, LocalSearchSolverLifecycleListener
public class LegacySimulatedAnnealingAcceptor
- extends AbstractAcceptor
TODO this will be removed once the time gradient based SimulatedAnnealingAcceptor
is always better.

LegacySimulatedAnnealingAcceptor
public LegacySimulatedAnnealingAcceptor()
setStartingTemperature
public void setStartingTemperature(double startingTemperature)
setTemperatureSurvival
public void setTemperatureSurvival(double temperatureSurvival)
solvingStarted
public void solvingStarted(LocalSearchSolverScope localSearchSolverScope)
- Specified by:
solvingStarted
in interface LocalSearchSolverLifecycleListener
- Overrides:
solvingStarted
in class AbstractAcceptor
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 LocalSearchSolverLifecycleListener
- Overrides:
stepTaken
in class AbstractAcceptor
