This question has been locked: [Efficient algorithm to find all the paths from A to Z?](https://stackoverflow.com/questions/8342101/efficient-algorithm-to-find-all-the-paths-from-a-to-z) because there were (apparently) too much comments under the original question. No arguing from me about that, although IMHO most of them were on-topic... 

But I can understand the comments being locked, and the discussion moved to chat. However, now that the entire question has been locked, one is not able to answer the question anymore. Is this normal? I'd understand it if the OP had accepted an answer, but this is not the case. 

Could it be unlocked please? Or if not, could someone explain the rationale behind locking an unaccepted question because there were too many comments?
