I think the
monte-carlo-search tag is currently ambiguous. The tag info page currently says:
For questions about clarifications/applications/implementation of the Monte Carlo Search algorithm used especially in Artificial Intelligence/Combinatorial games.
In computer science, Monte Carlo tree search (MCTS) is a heuristic search algorithm for some kinds of decision processes, most notably those employed in game play.
which implies that the tag is just about MCTS. However, the tag name itself (excluding the word "tree") implies that it is either:
- solely about plain "Monte Carlo Search" (which is, among game AI researchers, generally understood as a straightforward algorithm that evaluates children of the root by generating (semi-)random rollouts from the root node without any additional element of tree-building like in MCTS), or
- more generally about search techniques that somehow involve Monte-Carlo methods in whatever way you can think of.
The current usage of the tag appears to be (almost) exclusively about MCTS.
I propose one of the following two should happen:
Rename the tag to
monte-carlo-tree-search. This would remove ambiguity, and does not appear to conflict much (if at all) with usage of the tag so far.
Edit the tag info to be more generally about Monte-Carlo methods. Optionally, considering the popularity of the specific MCTS algorithm, I suppose a dedicated
monte-carlo-tree-searchtag could still be created as well.
