public class SimpleDispenser<T extends Chromosome>
extends ExclusiveDispenser<T>

Tutorial showing how to extend GeneticAlgorithm and how to use the flexible and configurable breeding structure in Jenes. The problem consists in searching a pattern of integers with a given precision. Solutions flow through two different crossovers in parallel. Some are processed by a single point crossover, the other by a double point crossover. After solutions are mutated. This class implements the strategy for dispensing solutions in the two branches. Odd solutions goes to the first, even to the second.
