€� traveling salesperson problem, Steiner tree. Finally, we assume that the reader knows something about NP-completeness, at least enough to know that there might be good reason for wanting fast, approximate solutions to NP-hard discrete optimization problems. TOP 30 IMPORTANT QUESTION OF Design & Analysis of Algorithm(DAA) For GBTU/MMTU C.S./I.T. They showed that this problem is NP-hard even to approximate, and presented several heuristic algorithms. A less obvious application is that the minimum spanning tree can be used to approximately solve the traveling salesman problem. Also Discuss What is meant by P(n)-approximation algorithm? Explain NP-Complete and NP- Hard problem. The expected value of a discrete random variable). Because all of these problems are NP-hard, the primary goal of this research is to produce polynomial-time, approximation algorithms for each problem considered. For graduate-level courses in approximation algorithms. One benefit of using Occam's Razor is that, if we're not One of the fascinating phenomenons of complexity is the dichotomy exhibited by many natural problems: they either have a polynomial-time algorithm (often with a low exponent) or are NP-hard, with very few examples in between. We present integer programs for both GOPs that provide exact solutions. It assumes familiarity with algorithms, mathematical proofs about the correctness of algorithms, probability theory and NP-completeness. We show both problems to be NP-hard and prove limits on approximation for both problems. Khot's Unique Games Conjecture (UGC) states that a certain approximation problem (known as “Unique Games” or UG) is NP hard. Approximation algorithms for NP-hard problems. In this problem, multiple missions compete for sensor resources.
