Is NP-complete a subset of NP?
Therefore, the NP-Complete set is also a subset of the NP-Hard set. NP-completeness applies to the realm of decision problems. It was set up this way because it’s easier to compare the difficulty of decision problems than that of optimization problems.
Is subset product NP-complete?
UPDATE: Turns out that subset product is only weakly NP-complete (the target product is exponential in Ω(n)).
Is the subset sum problem NP-complete?
The number of additions is at most n-1. So the addition and comparision can be done in polynomial time. Hence, SUBSET-SUM is in NP.
Is subset sum and knapsack problem NP-complete?
Clearly, the Knapsack (Subset Sum) Problem re- duces to the 0 -1 Knapsack Problem, and thus the 0 -1 Knapsack Problem is also NP-complete.
What is the difference between NP and NP-complete?
A problem X is NP-Complete if there is an NP problem Y, such that Y is reducible to X in polynomial time. NP-Complete problems are as hard as NP problems….Difference between NP-Hard and NP-Complete:
| NP-hard | NP-Complete |
|---|---|
| Do not have to be a Decision problem. | It is exclusively a Decision problem. |
Can an NP-complete language be in P?
Theorem: If any NP-complete language is in P, then P = NP. Theorem: If any NP-complete language is not in P, then P ≠ NP. its variables that makes it evaluate to true.
What are NP-complete problems?
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 do you understand by NP-complete is subset sum problem NP-complete if so explain?
Subset Sum is in NP: If any problem is in NP, then given a certificate, which is a solution to the problem and an instance of the problem (a set S of integer a1…aN and an integer K) we will be able to identify (whether the solution is correct or not) certificate in polynomial time.
Which of the following problem is not NP-complete?
Which of the following problems is not NP complete? Explanation: Hamiltonian circuit, bin packing, partition problems are NP complete problems. Halting problem is an undecidable problem.
What is NP-complete with example?
How do you prove NP-complete?
To show that a decision problem X is NP-complete, we prove that X is in NP (normally easy, and normally done by giving a suitable polynomial-time, non-deterministic algorithm) and then prove that X is NP-hard. To prove that X is NP-hard, we choose a known NP-complete problem, say A.
What makes a language NP-complete?
L. A language in L is called NP-complete iff L is NP-hard and L ∈ NP. The class NPC is the set of NP-complete problems. Theorem: If any NP-complete language is in P, then P = NP.
