Solved Problem 4 Np Complete Problem 10 Pts A Without Chegg

Solved Problem 4 10 Pts Solve Problem 4 10 Of The Chegg Problem 4 (np complete problem) 10 pts a. without using the cook levin theorem, show that the following problem is np complete: {(m, w, 1 t): m is a turing machine , ∃ y, ∣ y ∣ ≤ t, m (w, y) accepts after running ≤ t steps. } here 1 t denotes the number t in unary. in particular, you need to show that the above problem is in np and. Question 10 4 pts select all the true statements. a) p cnp b) a problem is in np if for all yes input, there is a certificate of this fact that can be verified in polynomial time. c) all decision problems are in np. d) suppose there is a polynomial time algorithm for an np complete problem, then p = np.

Solved Problem 4 10 Pts Consider The Following Figure 1 Chegg (e) (10 points) problem: bounded degree spanning tree instance: an undirected graph g = (v, e), and an integer k. question: is there a spanning tree of g such that the degree of every vertex, as measured with respect to the spanning tree, is

Solved 1 Please Explain A What Is The Np Complete Chegg 给定一个无向图g = (v, e) 和整数k ,是否可以对其顶点进行k染色? 我们来关注一类特殊的问题:判定问题。 [ 判定问题(decision problems)]. 这个问题是由多个np问题抽象而成，他具有多个np问题的基本性质，因此只要这个np complete问题解决了，与他关联的np complete问题也就能解决。 要成为np complete问题，第一步，他是np问题；第二步，其他所有np问题都能约化（抽象）成他。 如果一个决策问题 l 是 np complete的，那么l具备以下两个性质： 1) l 是 np （给定一个解决np complete的方案 (solution)， 可以很快验证是否可行，但不存在已知高效的方案 。 2) np里的任何问题可以 在多项式时间内转为 l。 npc类:是np的一个子集,且其中每一个问题均能由np中的任何问题在多项式时间内转化成. One notion of an "easier" np complete problem is if a ptas (polynomial time approximation scheme) exists for it. this basically means that for all small eps > 0, we can get within a factor of (1 eps) to the optimal solution in time polynomial in n and constant eps. an example of this is euclidean tsp. For example, the correct answer for the statement p=np is unknown. but the correct answer for the best algorithm for the maximum flow problem in n vertex graphs takes time at least 2^n'' is ``false''. give a short justification for your answer (i.e. explain why the statement is true, or false, or not known to be either true or false). Instance of a problem y can be solved using a polynomial number of standard computational steps, plus a polynomial number of calls to a, then we say y is polynomial time reducible to x, denoted. Provide a formal definition of the np complete decision problem. explain how the np complete problem is used to model the practical problem. (8 pts) provide an example of a positive instance of the np complete problem as well as an example of a negative instance. explain. (10 pts).
