virtual

This method selects an operator. The selection method is weelselction. Every operator has a propability p_i of selection which, is proportional to it's fitnessvalue plus the ratio of the fitnesssum of all operations divieded by the number of operations and 1000 .

minFitness = the minimum fitness (

See also:

cOperatorFitnessAlgorithm::getMinFitness()) minFitness2 = minFitness - fitnesssum / (#operations * 1000)) fitnesssum2 = fitnesssum - minFitness2 * #operations p_i = (fitness_i - minFitness2) / fitnesssum2

Returns:

a pointer to the choosen operator, or NULL if non can be selected Beware: You have to delete the returned object after usage.
