Class EnvironmentChangeDetectionStrategy<E extends PopulationBasedAlgorithm>

java.lang.Object
  net.sourceforge.cilib.pso.dynamic.detectionstrategies.EnvironmentChangeDetectionStrategy<E>

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

NeighbourhoodBestSentriesDetectionStrategy, PeriodicDetectionStrategy, RandomSentriesDetectionStrategy, RandomSentryDetectionStrategy, TopologyBestSentryDetectionStrategy

public abstract class EnvironmentChangeDetectionStrategy<E extends PopulationBasedAlgorithm>
extends Object
implements Cloneable, Serializable

This abstract class defines the interface that detection strategies have to adhere to. Detection strategies are used within the scope of a DynamicIterationStrategy to detect whether the environment has change during the course of an algorithm's execution.
