Method Detail

start

public void start(Experiment experiment,
                  List<IdSet> feasiblePool,
                  HeuristicCallback callback)
           throws InterruptedException

Description copied from interface: ImprovementHeuristic

Start the heuristic run. Use the information in the provided experiment to improve the provided pool (possibly only one) of feasible solutions.

Specified by:

start in interface ImprovementHeuristic

Parameters:

experiment - Experiment in context of which to run the heuristic.

feasiblePool - List of feasible solutions found so far.

callback - Callback to be invoked when finished.

Throws:

InterruptedException

getName

public String getName()

Description copied from interface: NamedModule

Returns a user friendly yet unique name of the module.

Specified by:

getName in interface NamedModule

Returns:

Unique module name.

getDisplayName

public String getDisplayName()

Description copied from interface: NamedModule

Returns a user friendly name of the module. This name is not neccessary unique.

Specified by:

getDisplayName in interface NamedModule

Returns:

Displayable module name.

getModuleDescription

public String getModuleDescription()

Description copied from interface: NamedModule

Returns the information about this module's inner workings. Most of the time will be equal to a call to NamedModule.getDisplayName(), but if the module for example consists of more sub-modules, their names should be listed here.

Specified by:

getModuleDescription in interface NamedModule

Returns:

String describing inner structure of the module.
