Now, as obvious a statement as that is in this algorithm, it turns out that is the key to this whole problem being solved correctly without my algorithm looping infinitely.

这是此算法中很明显的一句话，也是正确解决,整个问题的关键,否则此算法就会陷入死循环。

What is the class of algorithm that's- that probably applies to this, and how do I pull something out of that, if you like, a briefcase of possible algorithms to solve?

以及哪种算法-,可能可以应用到这类问题上,问题本身又能提取出什么东西来，以及可能解决问题的一系列方法的简介？

This is really the guts of the algorithm 'cause this line here, someone pointed it out before.

这才是算法的核心，因为在这儿，之前已经有人指出过。
