The problem would be to section the population of a state (currently California is debating this problem) so that each district has approximately the same population. This must be done without breaking city, county, or precinct boundaries. Also, in order to assure a fairly homogeneous constituency, the aspect ratio of the district must be limited. An optimal solution would have the smallest sum of district perimeters. -- BTK
