WebNP is finding the prime factors of very large numbers, in the realm of Google to Googleplex. Relations to Encryption: P is the "key" which allows us to decrypt the information when it reaches where it needs to go. NP encrypts the information with a long complex algorithm based on the concept of NP. algorithms. computer-science. Web1 Answer Sorted by: 43 I don't think there is any compelling evidence that integer factorization can be done in polynomial time. It's true that polynomial factoring can be, but lots of things are much easier for polynomials than for integers, and I see no reason to believe these rings must always have the same computational complexity. cheapest land prices by state

WebThe majority of research regarding the question, P = NP P = N P, deals with NP-\text {Complete} N P −Complete problems. NP-Complete problems have two basic properties: 1) It is in NP. 2) Every problem in NP is reducible to it in polynomial time.

WebNov 24, 2024 · Even finding one factoring $f_1$ which has the overall maximum saving $\textsf {{sav}}(f_1)$, is computationally hard. This NP-hardness result is established by a reduction from the NP-complete problem of finding maximum edge biclique in bipartite graphs . Theorem 2 (Hardness of factoring optimization). WebHowever, more pertinently, factorization is not known to be NP-complete, so even a polynomial time algorithm for it would not show that P=NP.

A special-purpose factoring algorithm's running time depends on the properties of the number to be factored or on one of its unknown factors: size, special form, etc. The parameters which determine the running time vary among algorithms. An important subclass of special-purpose factoring algorithms is the Category 1 or First Category algorithms, whose running time depends on the size of smallest prime factor.

WebApr 12, 2024 · NP-complete N P −complete problems are very special because any problem in the NP N P class can be transformed or reduced into NP-complete N P − complete problems in polynomial time. This means that if you can solve an NP-complete N P − complete problem, you can solve any other problem in NP N P. 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.

If there is a polynomial-time algorithm for any NP-complete problem, then P = NP, because any problem in NP has a polynomial-time reduction to each NP-complete problem. (That's actually how "NP-complete" is defined.) And obviously, if every NP-complete problem lies outside of P, this means that P ...

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 $\mathsf{NP\text{-}complete}$.

Share. cvs carytownWebAs an example, consider the problem of factoring an integer into primes. Over the course of my life, I must've met at least two dozen people who "knew" that factoring is NP-complete, and therefore that Shor's algorithm -- since it lets us factor on a quantum computer -- also lets us solve NP-complete problems on a quantum computer.
