Steve Cook was professor at Berkeley. He had come up with a, with a very peculiar theorem about a technical concept called a stack automaton. Vaughn Pratt also had independently discovered it a year or two later. So Steve had a way of transforming a computation that goes on and on and on into something that you can do on a regular computer fast. And so I tried it out on, on a problem where I knew a stack Automaton could do it, but I couldn't figure out a fast way to do it on a regular machine. The fact that it can do it at all means that there has to be a fast way.
