Our FAQ says that "algorithm and data structure concepts" questions are on-topic on Programmers. However, we receive "migrate to Stack Overflow" flags on a lot of algorithm-related question. This tells me there's a misunderstanding somewhere.
Do we want algorithm questions? What kind of questions are those?
Clearly questions about implementing an algorithm are off-topic, but are questions asking to derive an algorithm okay? Is that "conceptual" enough?
I like the idea of coming up with examples of good questions. So, what kinds of algorithm-related questions (if any) do you want to see on Programmers?
If there's a consensus reached here, we can amend the FAQ to be more clear about the kinds of algorithm-related questions we want or don't want.
