The GA Procedure

SetMutProb Call

call SetMutProb ( p ) ;

The SetMutProb call sets the mutation probability. The input to the SetMutProb subroutine is as follows:


is the mutation probability.

The SetMutProb subroutine is used to set the mutation probability for the genetic algorithm optimization. The probability p should be a number between 0 and 1, and is interpreted as the probability that a solution in the next generation should have the mutation operator applied to it. If a SetElite call has been made, then the elite solutions do not undergo mutation. Generally, a high mutation probability degrades the convergence of the genetic algorithm optimization, but some level of mutation is required to assure a thorough search and avoid premature convergence before the global optimum is found. Typical values for p are near 0.05 or less.
