WebJan 10, 2011 · This is simple actually. Multiplication is in P. NP is the same as "checking all possible polynomial sized solutions in parallel". If alpha is encoded as a length n bitstring, the factors total length is at most n + c. What it is not is "NP-complete". There is no way to turn an arbitrary NP problem into factoring. Share Follow WebIt seems that many people believe that P ≠ N P ∩ c o N P, in part because they believe that factoring is not polytime solvable. (Shiva Kintali has listed a few other candidate problems here ). On the other hand, Grötschel, Lovász, and Schrijver have written that "many people believe that P = N P ∩ c o N P ."

WebThe decision problem for factoring is $\mathsf {NP}$ and the factoring can be reduced to it in deterministic polynomial time. If $\mathsf {P}=\mathsf {NP}$ then then any problem in $\mathsf {NP}$ including factoring will have a polynomial time algorithm. WebFactoring is both in N P and B Q P (polynomial time quantum TM). This is not strange at all, e.g. every problem in P is also in both of them. Being in N P does not mean the problem is difficult, it is an upperbound on difficulty of the problem. …
