List of shouldTerminate() Examples

Examples of shouldTerminate()

de.mh4j.solver.termination.StagnationTermination.shouldTerminate()
de.mh4j.solver.termination.StepCountTermination.shouldTerminate()
de.mh4j.solver.termination.TerminationCondition.shouldTerminate()
org.uncommons.watchmaker.framework.TerminationCondition.shouldTerminate()
The condition is queried via this method to determine whether or not evolution should finish at the current point. @param populationData Information about the current state of evolution. This maybe used to determine whether evolution should continue or not. @return true if evolution should be terminated, false otherwise.
