I'm writing a distributed Go/Gomoku bot.
Basically the point is to distribute tree search onto many computers. With basic tree search algorithms like DFS this would be very simple, as I could just partition search space into subtrees. Though I'd rather have something more efficient, like mini-max with alpha-beta pruning - but from my understanding it's quite pointless without any kind of shared memory. So I'm kind of stuck.
Any ideas what algorithm could I use that's efficient and distributed easily? And more importantly, where can I find some (pseudo) code for it or maybe implementation?
Thanks,
You need to read up about Monte Carlo Tree Search, not because it's inherently easier to distribute (it is neither easier nor harder than another tree search), but because it's the state of the art and that people working on the problem are working on distributed version of that algorithm.
If you are going to the trouble of making a distributed algorithm, there's no reason to start with a lesser one. Unless you are making a distributed algorithm for educational reasons, in which case, go ahead, there will be something deeply educational in the experiment of distributing a basic algorithm and seeing it perform worse than the non-distributed state-of-the-art algorithm :)
