Package repast.simphony.parameter.optimizer

Class OptimizedParameterSweeper

java.lang.Object

repast.simphony.parameter.ParameterTreeSweeper

repast.simphony.parameter.optimizer.OptimizedParameterSweeper

All Implemented Interfaces:

ParameterSetter, ParameterSweeper

public class OptimizedParameterSweeper
extends ParameterTreeSweeper

A ParameterSweeper that attempts to traverse the space in an optimized manner. This does not necessarily traverse the entire parameter space, but will be lead through it's traversal by a traversal algorithm (a AdvancementChooser) which relies on a RunResultProducer to produce a single value for a run. This value is the value that is optimized through the search.
