Class TerminationCriteriaManager

java.lang.Object
de.uka.ipd.sdq.tcfmoop.tcmanager.TerminationCriteriaManager
All Implemented Interfaces:
IRequestManualTerminationListener, ITerminationCriteriaManager, org.opt4j.core.optimizer.OptimizerIterationListener
public class TerminationCriteriaManager extends Object implements ITerminationCriteriaManager
The main goal of the Termination Criteria Manager is to create termination criteria, call them so that they can evaluate the current optimization state and then evaluate their decisions, on which it must base its own decision whether to stop the optimization or not.

    • TerminationCriteriaManager

      @Inject public TerminationCriteriaManager(org.opt4j.core.optimizer.Control control, org.opt4j.core.optimizer.Population population, org.opt4j.core.optimizer.Archive archive)

  • Method Details

    • initialize

      public void initialize(List<IConfiguration> tcConfigurations)
      Initializes the termination criteria manager by supplying it with a list of termination criteria configurations.
      Specified by:
      initialize in interface ITerminationCriteriaManager

    • activateTCComparisionMode

      public void activateTCComparisionMode()
      Activates Termination Criteria Comparison Mode in which termination criteria decisions do not influence the optimization but are shown on the output.
      Specified by:
      activateTCComparisionMode in interface ITerminationCriteriaManager

    • deactivateTCComparisionMode

      public void deactivateTCComparisionMode()
      Deactivates Termination Criteria Comparison Mode in which termination criteria decisions are do not influence the optimization but are shown on the output.
      Specified by:
      deactivateTCComparisionMode in interface ITerminationCriteriaManager

    • activateComposedCriterion

      public void activateComposedCriterion()
      Activates Composed Criterion Mode in which multiple termination criteria can be stringed together to form a more powerful termination criterion
      Specified by:
      activateComposedCriterion in interface ITerminationCriteriaManager

    • deactivateComposedCriterion

      public void deactivateComposedCriterion()
      If Composed Criterion is deactivated then a simple || condition is used to evaluate results from the different criteria.
      Specified by:
      deactivateComposedCriterion in interface ITerminationCriteriaManager

    • setComposedCriterionExpression

      public void setComposedCriterionExpression(String composedCriterionExpression)
      Sets the expression used to define the relationship between the termination criterion. If not set a standard Expression is used (Crit1 || Crit2 || Crit3 || Crit4 || ...)
      Specified by:
      setComposedCriterionExpression in interface ITerminationCriteriaManager

    • evaluateTerminationCriteria

      public void evaluateTerminationCriteria()
      Evaluates the termination criteria and then stops the optimization if the specified conditions are met.
      Specified by:
      evaluateTerminationCriteria in interface ITerminationCriteriaManager

    • addOutputChangedListener

      public void addOutputChangedListener(IOutputChangedListener listener)
      Adds a new listener for the OutputChanged event. If the listener is also a IRequestManualTerminationProvider. the TCM will add itself as a listener to that event.

      listener - IOutputChangedListener listener

    • removeOutputChangedListener

      public void removeOutputChangedListener(IOutputChangedListener listener)
      Removes a new listener for the OutputChanged event. If the listener is also a IRequestManualTerminationProvider. the TCM will remove itself as a listener from that event.
      Specified by:
      removeOutputChangedListener in interface ITerminationCriteriaManager
      Parameters:
      listener - IOutputChangedListener listener
