# P=np explained simply

### Explained: P vs. NP MIT News Massachusetts Institute ..

One of these is the deceptively simple assertion that P = NP. In fact, in a 2002 poll, 61 mathematicians and computer scientists said that they thought P probably didn't equal NP, to only nine who thought it did — and of those nine, several told the pollster that they took the position just to be contrary The P versus NP problem is a major unsolved problem in computer science.It asks whether every problem whose solution can be quickly verified can also be solved quickly. It is one of the seven Millennium Prize Problems selected by the Clay Mathematics Institute, each of which carries a US\$1,000,000 prize for the first correct solution.. The informal term quickly, used above, means the existence. The P vs NP problem has paramount importance in the field of computer science and mathematics,it asks the very important question of whether a problem that is easily verifiable is easily solvable as well.Hence there comes the necessity to either prove or disprove if P equals NP Explained Simply - P vs NP. Recently I was asked to explain a complex topic simply. To prove the latter, P != NP, we would need to prove that all NP problems are actually NP-Complete (simply put, these are definitely hard problems, perhaps I'll explain this in another blog post) I'll do my best to explain (comment if I get something wrong). Also note I will cover the general background of the P = NP vs P != NP question for the sake of completeness, and because I think it's necessary to understand the answer to the questio..

Simply put: P = NP asks whether or not very computationally intensive algorithms that meet a certain criteria may have less computationally intense algorithms we just haven't figured out yet. More heuristically: From what I understand algorithms can be solved in polynomial time. IE, and xth order polynomial run time, where x is finite P=NP-problemet er et stort uløst problem innen matematikken og informatikken.Det er kjent som et av de sju millenniumsproblemene innen matematikken med en utlovet premie på 1 million dollar for ei løsning på problemet. Det går ut på om de to kompleksitetsklassene P og NP er like eller ikke. Det er flere måter å se problemstillinga på. Uformelt kan man si at problemet går ut på at. If P ≠ NP, there are problems in NP that are neither in P nor in NP-Complete. The problem belongs to class P if it's easy to find a solution for the problem. The problem belongs to NP, if it's easy to check a solution that may have been very tedious to find. Previous Page Print Page. Next Page

If exponential functions are transcendental functions, then they can not be expressed in a polynomial algebraic form. If so, then P≠NP. Is that so simple Feb 7, 2017 — Added Wikipedia attributions. March 2, 2014 — Cleaned up some of the explanation to avoid confusion. Notes. There is a class of NP problems that are NP-Complete, which means that if you solve them then you can use the same method to solve any other NP problem quickly.; This is a highly simplified explanation designed to acquaint people with the concept It's true in practice that solving NP-complete problems takes greater than polynomial time on a real computer, but that's not what it means, it's just the current state of the art, as a consequence of the fact that P=NP is unknown. If anyone found a polynomial algorithm to solve any NP-complete problem, that would prove P=NP, and we know that hasn't happened because it would be in the news

P vs NP Simply Explained 5. What's remarkable here is that all one needs to do to show that P = NP is to give an efficient algorithm for any NP-Complete problem. Just one! And yet to date, no one has, and computer scientists the world over have been trying since the 1970's Thus, P ⊆ NP. (It is also true, though harder to prove, that a deterministic Turing machine can be made which emulates the behaviour of any nondeterministic Turing machine. However, this requires the nondeterministic Turing machine's algorithm to be modified P vs. NP is one of the greatest unsolved problems. Just what is it, and why is it so important?

### P vs NP Problem Explained Is P Equal to NP? - Simple

1. Here is my attempt to explain P = NP to a hypothetical ten-year-old: If you have a Sudoku puzzle that hasn't been finished, and you want to finish it, that can be really hard to do. On the other hand, if your friend finishes the problem and you are good at arithmetic, it's not very hard to check to see if your friend's solution to the puzzle is right
2. It simply performs an exhaustive search over all witnesses. (Note that the maximum length of a witness is bounded by a polynomial.) So, your algorithm to decide PRIMES was actually a brute-force algorithm to decide COMPOSITE. NP is proper even in the case that P = NP
3. The simple notion of reduction is one of the most fundamental notions in complexity theory along with \$\mathsf{P}\$, \$\mathsf{NP}\$, and \$\mathsf{NP}\$-complete (which we will discuss below). The post has become too long and exceeds the limit of an answer (30000 characters)

If the answer is no, P =/= NP. If the answer is yes, P = NP. The solution doesn't have to scale quadratically, just at a rate of n^x for any X. If it scaled at n^1000 would still be in p, although in practice most practical problems in p people end up finding low-power solutions Hi mom! Okay, this is it! First, sit down, take a deep breath.

Yeah, I don't think that explained it well for the laymens. Here's my attempt at explaining P vs NP. With an NP problem, you can verify the solution quickly (in polynomial time) but you cannot generate the solution quickly.
