I should clarify that a bit. I would not run isolated GA's with small populations, high crossover rates, and low mutation rates in parallel. There would be a lot of wasteful reevaluation of individuals. I would run isolated algorithms with relatively high mutation rates in parallel. With high mutation rates, few individuals are evaluated more than once.
