Remove the restriction of one-move-per-round
The current code restricts each instance to one move per round. This is bad, as an computation restarted in the middle of the solution will have a different set of instances to work and will thus lead to a different end-solution. Once this is applied, further rounds are not possible since the first round will have tried all instances at its end. As such, the removal of the rounds feature will be next. The code adds a hard-coded 100 moves limit, which for big clusters is actually small.
