There's a tag algorithm-advice which is currently being used three times. All three questions were asking for help with solving a programming challenge found elsewhere. We usually consider that to be off-topic. Two of the questions were sort of salvaged and turned into challenges (the third one is still closed), but at that point they are no longer about algorithm advice, but about people competing for the winning criterion. So I think they shouldn't even have the tag any more.
A rather strong indicator that there's a correlation between the tag and bad/off-topic questions is that on top of those three remaining questions, there are 15 deleted ones with the tag.
If we really don't want algorithm advice questions, we should probably burninate the tag, because having it suggests that these questions are perfectly valid. Alternatively, we could sort out in which cases algorithm advice questions could be on topic here and outline that in the tag wiki.
