I propose to alias them up, and maybe use
chess-engines as master tag.
So you don't feel left hanging, I'm posting this as a notice that in a few days I'll default to a combination of ajax's and Nikana's suggestions, synonymizing the tags chess-engines, chess-computers, engines and computers, and additionally making engines the master of these, unless objections to doing so are raised/supported here.
I'm new to this exchange and missed this discussion, but I do have a strong objection to using
engines as the master tag; it is misleading. Some questions are about specific chess-playing engines, or about comparing them. Use the
engines tag for that.
Some questions are about more abstract computational concerns: are there promising AI algorithms? how many moves can we hope to compute in advance? I urge that this is reconsidered so we allow the more generic tag
computers for these questions.
