We tried initializing the pool of chromosomes with random chromosomes constructed by randomly selecting each area from the set of allowed values. These tended not to converge on valid solutions at all. We now instead take an approach for creating the initial population that is motivated by the standard design practice of starting with uniform sizes, or uniform sizes within subsets of members that serve a similar design purpose. The problem description did not include any information about the purpose of the various members, so we started with uniform sizes for all members. A chromosome was created in this fashion using each of the available sizes. As explained below, only some of these will have the full fitness evaluation.
