> Use Future's to spread all possible moves in each step over a number of threads.
> This number of threads is equal to the number of cpu's by default, as no IO is done during solving.
> Problems:
> - each thread will needs it own WorkingMemory and during a step, each working memory will need to be updated
> - a bunch of classes will need to be thread safe, or at least visibility save, such as bestsolutionrecaller.
> - Barriers will be needed to collect the result of each step
> - decks might be a great way to spread out the load
