WebPerhaps the most fundamental result in classical complexity theory is the Cook-Levin theorem [Coo71, Lev73], which states that SAT, the problem of deciding satis ability of a Boolean formula, is NP-complete. This result opened the door to the study of the rich theory of NP-completeness of constraint satisfaction problems (CSPs). stair tread stickers

The ability to use logspace reductions instead of polynomial time reductions to prove NP-completeness doesn't prove that P is contained in L.It just proves that you don't need the full power of polynomial time reductions to define NP-completeness.The situation is similar to saying, "Hey, there are lots of polynomial-time …

WebAn Alternative to the Cook-Levin Theorem. In general to prove that a given problem is NP-complete we show that a known NP-complete problem is reducible to it. This process is possible since Cook and Levin used the logical structure of NP to prove that SAT, and as a corollary 3-SAT, are NP-complete. This makes SAT the "first" NP-complete problem ...
