"WebThere are problems that are conjectured to be in NP ∩ CoNP but One is the problem of factoring an integer. The factoring problem is a functional problem: given a positive integer x, output a nontrivial factor of x, or say that xis prime. (Equivalently, output the entire prime factorization of x.)

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. 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.

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. … WebHere is my current sumOfDivisors () method: int sumOfDivisors (int n) { int sum = 1; int bound = (int) sqrt (n); for (int i = 2; i <= 1 + bound; i++) { if (n % i == 0) sum = sum + i + n / i; } return sum; } So I need to do lots of factorization and that is starting to become the real bottleneck in my application.
