All Implemented Interfaces:

public class InvalidFitnessValueException
extends java.lang.Exception

Exception thrown when an invalid fitness value is tried to be used

Default implementation throws this exception when the fitness value has a negative value in these cases. You should correct your fitness function for returning positive values.

Custom implementations of genetic algorithms may use other (problem spceific) criterias to throw this exception.

If fitness function returns negative values, then selectChromosome() method may return a negative index for individual. To prevent ArrayIndexOutOfBounds runtime exception, this exception is implemented. Other solutions are welcome, if you have.
