In 1971, Steve Cook gave his conference presentation that showed that SAT was
NP-complete. There it did not immediately stir up much excitement but it is, in
retrospect, the single most important conference talk in this history
of theoretical computer science. So when and where was this talk?
Steve Cook's paper The
Complexity of Theorem Proving Procedures appeared at the Third
Annual ACM Symposium on Theory of Computing (STOC) that was held May
3-5, 1971 in Shaker Heights, Ohio, a suburb of Cleveland.
Funda Ergun, a professor at Case Western Reserve, just purchased a
house in Shaker Heights and wondered where exactly the conference took
place. We got the answer from Bill Rounds, who
was one of the local organizers of that conference.
It was (at I think Stouffer's hotel) at the intersection of
Warrensville Center Road and Chagrin Boulevard, in the Van Aken center
district. The hotel is now gone.
