Exhaustive mode

[Weichi]

When players are working on problems at this website, the system usually randomly selects one move among all of it best moves. I was wondering if we could have an exhaustive mode, in which the player can try the problem multiple times and each time the computer responds with a different best move. After all the best moves of the computer has been exhausted, the round is over (or we say the problem is solved). I think this will help players better understand the problems.

that would be a nice improvement.

Maybe we can also have an exhaustive mode on the player side. That is, after the player solves the problem with one move, the system marks that move and tells the player to try other moves, if there are multiple ways to solve the problem.

yes, that's probably the best way to implement it. unfortunately, it's rather a lot of work...

I can imagine it must be a lot of work. But maybe we can start with a mode that is only exhaustive for the first step. In that case, we only need a loop instead of a tree-traversal algorithm.
