What is Crossover Probability & Mutation Probability in Genetic Algorithm or Genetic Programming?

Question

What is Crossover Probability & Mutation Probability in Genetic Algorithm or Genetic Programming ? Could someone explain them from implementation perspective!

Answer 1

According to Goldberg (Genetic Algorithms in Search, Optimization and Machine Learning) the probability of crossover is the probability that crossover will occur at a particular mating; that is, not all matings must reproduce by crossover, but one could choose Pc=1.0.

Probability of Mutation is per JohnIdol.
