Forgot to mention the indices set needed to define the range of permutations for a given population set used in Initialiser and Breeder. Also, if the population size > than the number of permutations due to all permutation sets then all permutations can be defined to guarantee a full range, rather than relying on random chance. Don't know if this will be useful or not. Predefining populations with input constraints due to known permutations will lower non-survivors, so an early population of full permutations may result in developing superior generations more quickly. Kinda looking forward to trying this one out. -- ray
