1. A method comprising: determining a plurality of sub-dimensional subsets, wherein the plurality of sub-dimensional subsets collectively define a restricted search space for an unbiased optimization of a plurality of variables in accordance with a plurality of objectives, wherein the restricted search space is only a portion of a total search space defined from the plurality of objectives; receiving a pair of chromosome data structures, wherein each of the pair of chromosome data structures provides a plurality of genes representative of the plurality of variables, wherein each of the plurality of variables are permitted to evolve in value; for each subset of the plurality of sub-dimensional subsets, the method further includes: selecting the respective subset for competition; determining a subset-winning chromosome data structure from the pair of chromosome data structures by considering at least one of (i) respective domination characteristics for respective ones of the pair of chromosome data structures based upon a competition between the pair of chromosome data structures, or (ii) respective diversity characteristics associated with respective ones of the pair of chromosome data structures; incrementing a unit of measure for the subset-winning chromosome data structure, wherein an amount accumulated for the unit of measure varies depending upon a respective subset ranking previously assigned to the subset-winning chromosome data structure, the respective subset ranking determined by performing domination sorting, restricted to the selected respective subset, for an entire population of chromosome data structures that included the subset-winning chromosome data structure; and determining an overall winning chromosome data structure of the pair of chromosome data structures by at least comparing a respective accumulated unit of measure for each of the pair of chromosome data structures, wherein the prior steps are performed by one or more computers.
