What are steps required to prove that a decision problem is NP-complete?
How many steps are required to prove that a decision problem is NP complete? Explanation: First, the problem should be NP. Next, it should be proved that every problem in NP is reducible to the problem in question in polynomial time.
What is a NP complete problem how you can prove a problem is NP-complete?
The idea is to take a known NP-Complete problem and reduce it to L. If polynomial time reduction is possible, we can prove that L is NP-Complete by transitivity of reduction (If a NP-Complete problem is reducible to L in polynomial time, then all problems are reducible to L in polynomial time).
Are all NP problems decision problems?
NP-complete problems are in NP, the set of all decision problems whose solutions can be verified in polynomial time; NP may be equivalently defined as the set of decision problems that can be solved in polynomial time on a non-deterministic Turing machine.

How do you know if a problem is NP?
A decision problem is in NP if there exists a polynomial time verification algorithm C(I,S) that takes both an input and a proposed solution, and verified whether the solution is ok, and satisfies the following properties: 1.
How do you prove that a language is NP-complete?
To prove that some language L is NP-complete, show that L ∈ NP, then reduce some known NP-complete problem to L. Do not reduce L to a known NP-complete problem. We already knew you could do this; every NP problems is reducible to any NP-complete problem!
