Improving Exponential-Time Algorithms for NP-Complete Problems
NP-complete problems cannot have deterministic polynomial-time algorithms unless P = NP. Due to their importance in practive, however, it is useful to improve their known exponential-time algorithms. We survey some of the recent results on such improved exponential-time algorithms for the NP-complete problems satisfiability, graph colorability, and domatic number.
