public class COptQuestFrontierMultiObjective
extends COptQuestMultiObjective

The COptQuestFrontierMultiObjective allows the user to combine objectives and treat them as a single objective for the optimization. This COptQuestFrontierMultiObjective does not find a single solution, rather it finds the "frontier" defining the trade-offs. The COptQuestFrontierMultiObjective is defined by adding COptQuestObjective objects to the COptQuestFrontierMultiObjective. The COptQuestFrontierMultiObjective object is then added to the COptQuestOptimization. The COptQuestFrontierMultiObjective is evaluated as maximizing an internal measure that changes as the search progresses. This internal measure is used to focus the search to find the points on the frontier.

Constructor Detail

COptQuestFrontierMultiObjective

public COptQuestFrontierMultiObjective()

Default constructor

COptQuestFrontierMultiObjective

public COptQuestFrontierMultiObjective(java.lang.String name)

Constructor that assigns a name to the objective

Parameters:

name -

Method Detail

AddObjective

public void AddObjective(COptQuestObjective obj)

Adds the input sub-objective to the COptQuestFrontierMultiObjective

Parameters:

obj -

SetFrontierSearchHeuristic

public void SetFrontierSearchHeuristic(COptQuestFrontierMultiObjective.FRONTIER_HEURISTIC heur)

For internal use. Sets the multi-objective search to use the defined search heuristic to find the points on the frontier.

SetFrontierSearchHeuristic

public void SetFrontierSearchHeuristic(COptQuestFrontierMultiObjective.FRONTIER_HEURISTIC heur,
                                       int algorithm)

For internal use. Sets the multi-objective search to use the defined search heuristic to find the points on the frontier.

SetObjectiveRange

public void SetObjectiveRange(COptQuestObjective obj,
                              double min,
                              double max)

Focuses the frontier search on objective values between min and max. If you are interested in a particular range for a given objective, set the min and max after the initial run (Optimize()) and then call OptimizeAdditional() to reduce the iterations needed for the search.

GetObjectiveMinimum

public double GetObjectiveMinimum(COptQuestObjective obj)

Returns the minimum set for a objective range.

Parameters:

obj -

Returns:

GetObjectiveMaximum

public double GetObjectiveMaximum(COptQuestObjective obj)

Returns the maximum value that was set for an objective range.

Parameters:

obj -

Returns:
