I get the impression that the tool has issues when used in this way (given the payload problems that have occurred with these four recently submitted ‘Change Subnet Membership’ proposals - 5kdm2, mpubz, tdb26, uzr34).
I’m quite interested in writing an alternative tool from the ground up using a different optimisation approach (non-greedy, non-linear, stochastically optimised using something like a simulated annealing algorithm - or whatever does a better job of avoiding local minima). I’m also interested in optimising for the fewest number of swaps required to meet arbitrary targets.
Does this sound like something that would be useful (I’d open source it of course)?
