NP-complete Problems and Physical Reality
... Of course, even if there is no deterministic algorithm to solve NP-complete problems in polynomial time, there might be a probabilistic algorithm, or a nonuniform algorithm (one that is different for each input length n). But Karp and Lipton [53] showed that either of these would have a consequence, ...
