### NP-Problem -- from Wolfram MathWorl

NP-Problem. A problem is assigned to the NP (nondeterministic polynomial time) class if it is solvable in polynomial time by a nondeterministic Turing machine.. A P-problem (whose solution time is bounded by a polynomial) is always also NP. If a problem is known to be NP, and a solution to the problem is somehow known, then demonstrating the correctness of the solution can always be reduced to. 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. 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. Innenfor informatikk og matematikk, er NP-komplette problemer en mengde med svært vanskelige problemer. Et problem blir ofte kalt lett dersom problemet kan løses på kort tid, og dette blir ofte målt som polynomisk tid; et vanskelig problem er et problem som ikke kan løses på kort tid.Et av matematikkens aller største åpne problemer i dag er om NP-komplette problemer er «lette» NP-complete problem, any of a class of computational problems for which no efficient solution algorithm has been found. Many significant computer-science problems belong to this class—e.g., the traveling salesman problem, satisfiability problems, and graph-covering problems. So-called easy, o

P versus NP problem, in full polynomial versus nondeterministic polynomial problem, in computational complexity (a subfield of theoretical computer science and mathematics), the question of whether all so-called NP problems are actually P problems. A P problem is one that can be solved in polynomial time, which means that an algorithm exists for its solution such that the number of. NP-complete problems are the hardest problems in NP set. A decision problem L is NP-complete if: 1) L is in NP (Any given solution for NP-complete problems can be verified quickly, but there is no efficient known solution). 2) Every problem in NP is reducible to L in polynomial time (Reduction is defined below)

NP-Complete problems can be solved by deterministic algorithm in polynomial time. To solve this problem, it must be a NP problem. To solve this problem, it must be both NP and NP-hard problem Every problem in this class can be solved in exponential time using exhaustive search. P versus NP. Every decision problem that is solvable by a deterministic polynomial time algorithm is also solvable by a polynomial time non-deterministic algorithm It Means No problem. A term coined by Donald Trump on his show The Apprentice even though bosses used it all the time before.Now anyone who watched five minutes of it thinks it's THE ABSOLUTE SHIT and uses it to say YOU SUCK! or LOSER

NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve. Perhaps the most famous exponential-time problem in NP, for example, is finding prime factors of a large number NP-Complete may not last. Oh, one more thing, it is believed that if anyone could *ever* solve an NP-Complete problem in P time, then *all* NP-complete problems could also be solved that way by using the same method, and the whole class of NP-Complete would cease to exist. Traveling Salesman Problem P versus NP is the following question of interest to people working with computers and in mathematics: Can every solved problem whose answer can be checked quickly by a computer also be quickly solved by a computer?P and NP are the two types of maths problems referred to: P problems are fast for computers to solve, and so are considered easy 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 NP-Complete-- The group of problems which are both in NP and NP-hard are known as NP-Complete problem. Now suppose we have a NP-Complete problem R and it is reducible to Q then Q is at least as hard as R and since R is an NP-hard problem. therefore Q will also be at least NP-hard , it may be NP-complete also

By Ayesha Ahmed. Creativity, ingenuity, luck. All concepts that set apart the most brilliant minds from the rest. But also concepts we cannot strictly define. After all, there are no set of rules for genius. Well, actually, there might be. This idea is exactly what the P vs. NP problem attempts to encapsulate: can we create a map of achieving creativity NP-complete problems are defined in a precise sense as the hardest problems in P. Even though we don't know whether there is any problem in NP that is not in P, we can point to an NP-complete problem and say that if there are any hard problems in NP, that problems is one of the hard ones

NP-Hard is the set where problems are at least as hard as NP. Any problem in NP could be transformed to NP-Hard problem in polynomial time. These problems cannot be solved in polynomial time if P is not equal to NP. That is when the hardest problem in NP is polynomial time solvable then only NP-Hard problems are polynomial time solvable Get a free audiobook and a 30-day trial of Audible (and support this channel) at http://www.audible.com/upandatom or text upandatom to 500 500 on your phon.. To explain , , and others, let's use the same mindset that we use to classify problems in real life. While we could use a wide range of terms to classify problems, in most cases we use an Easy-to-Hard scale. Now, in theoretical computer science, the classification and complexity of common problem definitions have two major sets; which is Polynomial time and which Non.

### P versus NP problem - Wikipedi

P Vs Np Problem. A superset of P is a class called NP. These are all the problems where if you're given a correct solution you can at least check it in a reasonable amount of time but computing. NP-Complete Problem. A problem which is both NP (verifiable in nondeterministic polynomial time) and NP-hard (any NP-problem can be translated into this problem). Examples of NP-hard problems include the Hamiltonian cycle and traveling salesman problems.. In a landmark paper, Karp (1972) showed that 21 intractable combinatorial computational problems are all NP-complete P versus NP. Is it even solvable? 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.It is the most recently conceived problem of the seven (in 1971) and also the easiest to explain (hopefully) A problem is in the class NPC if it is in NP and is as hard as any problem in NP. A problem is NP-hard if all problems in NP are polynomial time reducible to it, even though it may not be in NP itself.. If a polynomial time algorithm exists for any of these problems, all problems in NP would be polynomial time solvable NP-complete problems 8.1 Search problems Over the past seven chapters we have developed algorithms for nding shortest paths and A search problem is specied by an algorithm Cthat takes two inputs, an instance Iand a proposed solution S, and runs in time polynomial in jIj

What is the abbreviation for No Problem? What does NP stand for? NP abbreviation stands for No Problem Definition of no problem in the Idioms Dictionary. no problem phrase. What does no problem expression mean? Definitions by the largest Idiom Dictionary. No problem and No prob and NP phr. All is well.; There is no problem, so don't worry or fret. (Often said after someone else says I'm sorry.) No problem. I can do it easily. A: Gee! I. First of all we give some reasons that natural proofs built not a barrier to prove P \$\\not=\$ NP using Boolean complexity. Then we investigate the approximation method for its extension to prove super-polynomial lower bounds for the non-monotone complexity of suitable Boolean functions in NP or to understand why this is not possible. It is given some evidence that the approximation method. As mentioned above, NP is used as an acronym in text messages to represent No Problem. This page is all about the acronym of NP and its meanings as No Problem. Please note that No Problem is not the only meaning of NP. There may be more than one definition of NP, so check it out on our dictionary for all meanings of NP one by one

NP-complete problems are the hardest in NP: if any NP-complete problem is p-time solvable, then all problems in NP are p-time solvable How to formally compare easiness/hardness of problems? Reductions Reduce language L 1 to L 2 via function f: 1. Convert input x of L 1 to instance f(x) of L 2 2 NP-Complete. NP-Complete is a complexity class which represents the set of all problems X in NP for which it is possible to reduce any other NP problem Y to X in polynomial time.. Intuitively this means that we can solve Y quickly if we know how to solve X quickly. Precisely, Y is reducible to X, if there is a polynomial time algorithm f to transform instances y of Y to instances x = f(y) of X. Don't see what you need? Just ask and we will try to source it and quote you a price This is an example of what computer scientists call an NP-problem, since it is easy to check if a given choice of one hundred students proposed by a coworker is satisfactory (i.e., no pair taken from your coworker's list also appears on the list from the Dean's office), however the task of generating such a list from scratch seems to be so hard as to be completely impractical

A2A Michel Alexandre Salim's answer is correct. Sudoku is NP, NP-Hard, and NP-Complete. But there's a caveat, as there is with many problems which we refer to as NP-Complete. Those terms all refer to decision problems, that is problems that have a.. NP-complete (complexity) (NPC, Nondeterministic Polynomial time complete) A set or property of computational decision problems which is a subset of NP (i.e. can be solved by a nondeterministic Turing Machine in polynomial time), with the additional property that it is also NP-hard. Thus a solution for one NP-complete problem would solve all problems in. 16.3 NP-hard, NP-easy, and NP-complete A problem is NP-hard if a polynomial-time algorithm for would imply a polynomial-time algorithm for every problem in NP. In other words: is NP-hard If can be solved in polynomial time, then P=NP Intuitively, this is like saying that if we could solve one particular NP-hard problem quickly, the

Dpla As noted in the earlier answers, NP-hard means that any problem in NP can be reduced to it. This means that any complete problem for a class (e.g. PSPACE) which contains NP is also NP-hard. In order to get a problem which is NP-hard but not NP-complete, it suffices to find a computational class which (a) has complete problems, (b) provably contains NP, and (c) is provably different from NP

\$\mathsf{NP}\$ = Problems with Efficient Algorithms for Verifying Proofs/Certificates/Witnesses Sometimes we do not know any efficient way of finding the answer to a decision problem, however if someone tells us the answer and gives us a proof we can efficiently verify that the answer is correct by checking the proof to see if it is a valid proof.This is the idea behind the complexity class. In Theoretical Computer Science, the two most basic classes of problems are P and NP. P includes all problems that can be solved efficiently. For example: add two numbers. The formal definition of efficiently is in time that's polynomial in the. The certificate to the problem might be vertices in order of Hamiltonian cycle traversal. We can check if this cycle is Hamiltonian in linear time. It is called verification. So, the problem belongs to . Moreover, it can be proven that the Hamiltonian Cycle is -Complete by reducing this problem to 3SAT. 3.2. How to Show a Problem Is NP-Hard

• Formally, a problem is NP-hard if given an oracle machine for the problem, all other problems in NP could be solved in polynomial time. The best known example of a problem that is in NP, but thought not to be NP-hard, is integer factorization
• You may have heard of the famous P versus NP problem. If you can prove or disprove its cryptically short equation, you'd be a million dollars richer—and maybe even billions of dollars richer.
• Some First NP-complete problem We need to nd some rst NP-complete problem. Finding the rst NP-complete problem was the result of the Cook-Levin theorem. We'll deal with this later. For now, trust me that: Independent Set is a packing problem and is NP-complete. Vertex Cover is a covering problem and is NP-complete

• NP. See also NP-hard, P. Note: A trivial example of NP, but (presumably) not NP-complete is finding the bitwise AND of two strings of N boolean bits. The problem is NP, since one can quickly (in time Θ(N)) verify that the answer is correct, but knowing how to AND two bit strings doesn't help one quickly find, say, a Hamiltonian cycle or tour.

NP means No Problem. The abbreviation NP is widely used in text-based messaging with the meaning No Problem. NP is typically used as a positive response to a request (i.e., to say Yes) and as a response to someone saying thank you (i.e., to say You're welcome). (See examples below.) NP is one of many abbreviations with similar meanings. Another NP-complete problem is to decide if there exist k star-shaped polygons whose union is equal to a given simple polygon, for some parameter k. The optimization problem, i.e., finding the minimum number (least k) of star-shaped polygons whose union is equal to a given simple polygon, is NP-hard
