Who solved P vs NP?

New Delhi: Vinay Deolalikar, a scientist at HP (Hewlett-Packard) Labs in California, has proposed a possible proof for the famed P=NP problem in mathematics—a feat that could net him $1 million (Rs4. 6 crore) for solving one of the seven Clay Mathematics Institute Millennium Problems.

What is P and NP in computer science?

P is the set of problems whose solution times are proportional to polynomials involving N's. ... 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.

What happens if P vs NP is solved?

If P equals NP, every NP problem would contain a hidden shortcut, allowing computers to quickly find perfect solutions to them. But if P does not equal NP, then no such shortcuts exist, and computers' problem-solving powers will remain fundamentally and permanently limited.

Is P NP solvable?

P is the set of all decision problems that are efficiently solvable. P is a subset of NP. P is the set of all decision problems that are efficiently solvable and is a subset of NP. Basic Arithmetic is solvable in Polynomial-time, thus belongs to P.

What are the 7 hardest math problems?

The problems are the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Poincaré conjecture, Riemann hypothesis, and Yang–Mills existence and mass gap.

What is the hardest math problem in the world?

But those itching for their Good Will Hunting moment, the Guinness Book of Records puts Goldbach's Conjecture as the current longest-standing maths problem, which has been around for 257 years. It states that every even number is the sum of two prime numbers: for example, 53 + . So far so simple.

What is NP problem example?

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.

What is the relation between P and NP class problems?

NP is set of problems that can be solved by a Non-deterministic Turing Machine in Polynomial time. P is subset of NP (any problem that can be solved by deterministic machine in polynomial time can also be solved by non-deterministic machine in polynomial time) but P≠NP.

Is P NP or P ≠ NP?

According to polls, most computer scientists believe that P ≠ NP. A key reason for this belief is that after decades of studying these problems no one has been able to find a polynomial-time algorithm for any of more than 3000 important known NP-complete problems (see List of NP-complete problems).

Is everything in P in NP?

A yes-or-no problem is in P (Polynomial time) if the answer can be computed in polynomial time. A yes-or-no problem is in NP (Non-deterministic Polynomial time) if a yes answer can be verified in polynomial time.

What does NP-hard stand for?

non-deterministic polynomial-time hardness In computational complexity theory, NP-hardness (non-deterministic polynomial-time hardness) is the defining property of a class of problems that are informally "at least as hard as the hardest problems in NP".

What is the hardest math class?

Math 55 “Math 55” has gained a reputation as the toughest undergraduate math class at Harvard—and by that assessment, maybe in the world. The course is one many students dread, while some sign up out of pure curiosity, to see what all the fuss is about.

What is the easiest math problem ever?

If by 'simplest' you mean easiest to explain, then it's arguably the so-called 'Twin Prime Conjecture'. Even schoolchildren can understand it, but proving it has so far defeated the world's best mathematicians. Prime numbers are the building blocks from which every whole number can be made.

How do you prove P NP?

One way to prove that P = NP is to show that the complexity measure TM (n) for some NP problem, like the 3-CNF-SAT problem, cannot be reduced to a polynomial time. We will show that the 3-CNF-SAT problem behaves as a common safe problem and that its complexity is time dependent.

What does it mean if Q is NP-hard?

A problem is NP-hard if an algorithm for solving it can be translated into one for solving any NP- problem (nondeterministic polynomial time) problem. NP-hard therefore means "at least as hard as any NP-problem," although it might, in fact, be harder.

What is NP-hard problem with example?

An example of an NP-hard problem is the decision subset sum problem: given a set of integers, does any non-empty subset of them add up to zero? That is a decision problem and happens to be NP-complete.

Is every P problem in NP?

Every deterministic Turing machine is a special case of—and no stronger than—a non-deterministic Turing machine. Therefore, if a problem is in P, i.e. is solvable in polynomial time by a deterministic TM, then it is solvable by that same TM this time regarded as non-deterministic, hence is in NP. Yes.

What is the hardest math problem?

But those itching for their Good Will Hunting moment, the Guinness Book of Records puts Goldbach's Conjecture as the current longest-standing maths problem, which has been around for 257 years. It states that every even number is the sum of two prime numbers: for example, 53 + . So far so simple.

Does NP mean Nope?

@Psp: nop/np or nope means "no" it is used in informal.
