All Implemented Interfaces:

InteractionModel, java.io.Serializable

public class HistoryWindowIM

extends ShellIM

This interaction model keeps the last H elites it has seen in a Vector during evolution. If it ever encounters an elite which is less fit than the previous generation's, it will insert the individual that was the elite H generations ago into the population. This is particularly useful to avoid bad mutants replacing superior elites in noisy (1+1) ES runs.
