Explain all types of Selection in detail.
1 Answer


Fitness proportionate selection:

  • In our prototypical GA shown in the above Table, the probability that a hypothesis will be selected is given by the ratio of its fitness to the fitness of other members of the current population as seen in the Equation above. This method is sometimes called fitness proportionate selection.

Tournament selection:

  • Other methods for using fitness to select hypotheses have also been proposed. For example, in tournament selection, two hypotheses are first chosen at random from the current population.

Rank selection:

  • Tournament selection often yields a more diverse population than fitness proportionate selection. In another method called rank selection, the hypotheses in the current population are first sorted by fitness.
