Why is the optimization phase not evaluating all of the chromosomes (tests) in a generation?
When the genetic algorithm used in the genetic optimization phase produces a new generation, it is possible that chromosomes will be produced that are the same as those in the previous generation. If a chromosome has been evaluated in a previous generation, it is not re-evaluated. The likelihood of duplicate chromosomes being produced can be reduced by increasing the mutation rate on the Modify Genetic Algorithm Settings Dialog. This will make it more likely that random elements will be introduced into the population. However, this can also make it more difficult to evolve better chromosomes from previous best chromosomes.
