In Simple Words,

• NP-Class--- It is a set of decision problems that are not solvable but are verifiable in polynomial time

• NP Complete--- It is one of the decision problem that belong to NP Class and all the problems in NP Class can be reduced to this problem..
• Implies that if this problem is solvable in polynomial time then all other NP Problems can be solved in Polynomial time..

• NP Hard--- NP Hard Contains those problems which may or may not belong to NP-Class but are all reducible to NP Class problem..
• It Simply means that there are some problems like set of optimization problem that are harder to solve then NP class.. All those problems which are not decision problems and are not solvable in Polynomial Time Belong the This Set...
• Implies that if this kind of a problem is solvable in polynomial time then all other NP class problems will be solved in Polynomial Time...

good efert

Some problems can be translated into one another in such a way that a fast solution to one problem would automatically give us a fast solution to the other. There are some problems that every single problem in NP can be translated into, and a fast solution to such a problem would automatically give us a fast solution to every problem in NP. This group of problems are known as NP-Hard. Some problems in NP-Hard are actually not themselves in NP; the group of problems that are in both NP and NP-Hard is called NP-Complete.

well don bro . keep it up

krna kia hy.... NP, NP-compelete ...... in sab koexplain krna hy ya in ka relation btanan hy ya phir defference smj nai arha some one please help

I think, we just need to explain, as it is mentioned that, words should not be more than 100 words.

The question is --> You are required to support or contradict or other logical comments upon  above statement by giving solid reasoning;
The statement is -->
“NP, NP-Complete and NP-Hard problems have always efficient Verifiers/Deciders “
So, we have to explain whether the NP, NP-Complete and NP-Hard problems have always efficient Verifiers/Deciders or not, with solid reason.

koi samaj nai a rahi plzzzzzzzzz help krain time bohat kam ha

plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz share right solution as soon as possibal
