What Makes A Problem NP-complete? A problem is called NP (nondeterministic polynomial) if its solution can be guessed and verified in polynomial time; nondeterministic means that no particular rule is followed to make the guess. If a problem is NP and all other NP problems How do you prove a problem is NP-complete? Suppose X
What Is P And NP Class Problems? In this theory, the class P consists of all those decision problems (defined below) that can be solved on a deterministic sequential machine in an amount of time that is polynomial in the size of the input; the class NP consists of all those decision problems whose positive
How Do You Know If You Have A NP-hard Problem? A problem is said to be NP-hard if everything in NP can be transformed in polynomial time into it even though it may not be in NP. Conversely, a problem is NP-complete if it is both in NP and NP-hard. … If some NP-complete problem
Is Halting A Problem With NP? It is also easy to see that the halting problem is not in NP since all problems in NP are decidable in a finite number of operations, but the halting problem, in general, is undecidable. There are also NP-hard problems that are neither NP-complete nor Undecidable. Are halts NP?
Is Circuit Sat NP-complete? Theorem 1 CIRCUIT-SAT is NP-complete. Proof It is clear that CIRCUIT-SAT is in NP since a nondeterministic machine can guess an assignment and then evaluate the circuit in polynomial time. … And C can be constructed in polynomial time given the length of x and y. Is Circuit sat an NP?
Is The Knapsack Problem NP-complete? The decision problem form of the knapsack problem (Can a value of at least V be achieved without exceeding the weight W?) is NP-complete, thus there is no known algorithm both correct and fast (polynomial-time) in all cases. … There is a pseudo-polynomial time algorithm using dynamic programming. How do
What Do You Mean By Polynomial Reduction? In computational complexity theory, a polynomial-time reduction is a method for solving one problem using another. … If both the time required to transform the first problem to the second, and the number of times the subroutine is called is polynomial, then the first problem is polynomial-time reducible
Can A Hamiltonian Cycle Use Polynomial Time? With the construction, any graph with a vertex cover, can be used to make a graph with a Hamiltonian Cycle graph. Since creating such a graph can be done under polynomial time, simply replace edges with widgets and make proper connections, we have a reduction from Vertex Cover
