11. Equivalently, any improvement on these running times would falsify the strong exponential time hypothesis. 12. All the best-known algorithms for NP-complete problems like 3SAT etc . take exponential time . 13. Currently, there is no known sub-exponential time algorithm that can solve this problem deterministically. 14. Showed that finding-vertex cliques cannot be done in time unless the exponential time hypothesis fails. 15. Even when they terminate, parsers that use recursive descent with backtracking may require exponential time . 16. "Evolution doesn't reward proteins that take an exponential time to fold up, " he said. 17. The exponential time hypothesis implies P ` " NP. 18. At the cost of a potentially exponential time increase, loops can be detected space-efficiently as follows: 19. However, if the strong exponential time hypothesis fails, it would still be possible for " s" 20. For example, an exponential time algorithm can sometimes still be fast enough to make a feasible attack.
