Constructor Summary

AsyncGeneticAlgorithm()
Create an instance of an Asynchronous Genetic Algorithm.

AsyncGeneticAlgorithm(java.lang.Class c, java.lang.Class f)
Create an instance of an Asynchronous GA with a specified organism class and a specified fitness class.

Method Summary

void	evaluate(Organism org) Specify how a certain organism is evaluated.
Arc	getIncumbent() return the Incumbent (best) organism.
java.lang.Object	run(boolean distributed) This method provides the sequence of various steps involved in a GA.
void	setIncumbent(Organism org) sets the Incumbent (best) organism.
void	updateSuccessor(AsyncPopulation suc) Once the evolve nodes in a certain generations complete, the pointers to the successor population are updated.
