All Implemented Interfaces:: AgentConstants, EnvironmentConstants, UtilitiesMath, UtilitiesRandom, UtilitiesString, Serializable

public abstract class ExperimentOptimization<ROOT extends Agent>
extends ExperimentMultipleRuns<ROOT>

addSuggestedSolution

@AnyLogicInternalCodegenAPI
public void addSuggestedSolution()

This method signals the completion of a suggested solution definition.
#setParameterVariableSuggestedValue(COptQuestVariable, double) is used to set a value for each variable.
This method signals a value has been set for each variable.
The solution is added to the set of suggested solution and will be one of the first solutions evaluated if the optimization has not started.
If the optimization is running, the suggested solution will be one of the next solutions to be evaluated

This is optimization setup method, user should not call it

setMaximumIterations

@AnyLogicInternalCodegenAPI
public void setMaximumIterations(int numberOfIterations)

Sets the number of iterations the optimization should perform before stopping. If multiple stop options are set, the optimization will stop at the first option that is satisfied

This is optimization setup method, user should not call it

Parameters:: numberOfIterations - number of optimization iterations to be performed

setAutoStop

@AnyLogicInternalCodegenAPI
public void setAutoStop(boolean stop)

Sets the auto stop option.
If the input parameter is true, auto stop is turned on. The default is auto stop is turned off.
OptQuest uses different techniques to search for a better solution and cycles through them when determines that the current technique stops helping to improve the solution. When automatic stop is set, the optimization stops when OptQuest has already cycled through all of its techniques for two (default) times. This method is an equivalent of getOptimization().SetAutoStopByCycles(stop);

This is optimization setup method, user should not call it

Parameters:: stop - true if auto stop is to be used, false if it is not used

setUserControlledStop

@AnyLogicInternalCodegenAPI
