What does P and NP stand for?

nondeterministic polynomial time 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 is P class and NP problem?

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. 18.

Who Solved P versus NP problem?

In 2000 American mathematician Stephen Smale devised an influential list of 18 important mathematical problems for solving in the 21st century. The third problem on his list was the P versus NP problem.

Does anyone think P NP?

P ≠ NP is about all possible algorithms to solve a problem. The reason people are skeptical of proof attempts of P!= NP is the same reason that people are skeptical of proofs of any famous conjecture: false proofs are published every few months and shot down.

Can humans solve NP problems?

With humans, we do not have a well defined model of how our brains compute. ... Without such a model, there cannot be a mathematical proof that the human brain can or cannot solve NP-complete problems in polynomial time.

Which country has toughest maths?

But when it comes to having the hardest math, China and South Korea top the list.

What is the 1 million dollar math problem?

A correct solution to any of the problems results in a US$1 million prize being awarded by the institute to the discoverer(s). To date, the only Millennium Prize problem to have been solved is the Poincaré conjecture, which was solved in 2003 by the Russian mathematician Grigori Perelman. He declined the prize money.

Has P != NP been proven?

NP is probably the most important problem in theoretical computer science, with $1M prize. Vinay Deolalikar at HP Labs has released a preliminary 100+ page proof that P != NP.

Is NP equal to P?

6 Answers. P stands for polynomial time. NP stands for non-deterministic polynomial time.

Can a problem be P and NP?

There are a large number of important problems that are known to be NP-complete (basically, if any these problems are proven to be in P, then all NP problems are proven to be in P). If P = NP, then all of these problems will be proven to have an efficient (polynomial time) solution. Most scientists believe that P!= NP.

Is Floyd warshall NP-hard problem?

It is not NP-complete, because it is not a decision problem. In weighted complete graphs with non-negative edge weights, the weighted longest path problem is the same as the Travelling salesman path problem, because the longest path always includes all vertices.

Can biological quantum networks solve NP hard problems?

There is a widespread view that the human brain is so complex that it cannot be efficiently simulated by universal Turing machines. So, the conclusion is that biological quantum networks can only approximately solve small instances of NP-hard problems. ...
