Is integer factorization an NP-complete problem?

WebCaveat: PRIME, FACTOR not known to be NP-complete. 22 The "World’s First" NP-Complete Problem CNF-SAT is NP-complete. (Cook-Levin, 1960’s) Idea of proof: Given problem X in NP, by definition, there exists nondeterministic TM M that solves X in polynomial time. Possible execution of M on input string s forms a WebBeing in $\mathsf{NP}$ does not mean the problem is difficult, it is an upperbound on difficulty of the problem. A problem in $\mathsf{NP}$ can be arbitrary easy. I am guessing that you are confusing $\mathsf{NP}$ and $\mathsf{NP\text{-}complete}$. It is not known (in fact very unlikely) that Factoring is $\mathsf{NP\text{-}complete}$. the influence of bible on english language

Is integer factorization an NP-complete problem?

WebNo, its not known to be NP-complete, and it would be very surprising if it were. This is because its decision version is known to be in NP ∩ co-NP. (Decision version: Does n have a prime factor < k ?) It is in NP, because a factor p < k such that p ∣ n serves as a witness of … WebJan 10, 2011 · 2. 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.

WebMay 3, 2024 · By definition, if you were to find a polynomial time algorithm for an NP-hard (or NP-complete) problem, then P = N P. So, short answer is - no. However, its possible to think instead of solving the problems fully, to approximate a solution, or to solve them randomly. WebA problem is in NP if and only if it has a polynomial verifier – that's the definition of NP. All NP-complete problems are in NP – that's part of the definition – and so have a polynomial …
