math guru's normally cannot tell you what to do in such a situation, they often only can tell you if your solution is correct, optimal, or if a solution exists at all
in JoeBOT XP, i havn't any randomization yet, because the task system for the squads isnt ready yet. a squad just choses a random location and then they go there. the only cost penalties are at the moment connections where bots got previously stuck and connection which are already run along by teammates to avoid running in one line like ducks. random doesnt look that stupid
