You could change the official rule to add a condition so that only maps that meet minority majority distracting requirements (say 55%) are considered valid. The eliminates the post processing required. You pick the "best" map such that it has less than 1% population imbalance and has at least a 55% majority for each "designated minority" district. Even with a PR method the VRA could apply. For example, if there was 10 seats and 2 districts, and an ethnic group had 10% of the population, then you could prevent them from achieving a seat by splitting them so that they are evenly split between each district. This would give them 10% in each district, which isn't enough to reach the quota. So, a rule that boundaries should not split communities of interest would still be a reasonable rule. ---- Election-Methods mailing list - see http://electorama.com/em for list info
