Approximation Algorithm vs Heuristic. Presented at Computer Science Department, Sharif University of Technology (Optimization Seminar ). We would then do better by trying to design a good approximation algorithm rather than searching endlessly seeking an exact solution. Study of low-distortion embeddings (which can be pursued in a more general setting) has been a highly-active TCS research topic, largely due to its role in designing efficient approximation algorithms for NP-hard problems. Thus unless P = NP, there are no efficient algorithms to find optimal solutions to such problems. This is one of Karp's original NP-complete problems. Often, when dealing with the class NPO, one is interested in optimization problems for which the decision versions are NP-hard. Yet most such problems are NP-hard. Even if P is not equal to NP, there may be randomized algorithms (either Monte Carlo or Las Vegas) that can answer NP hard problems rapidly. Also Discuss What is meant by P(n)-approximation algorithm? Instead of trying to solve this problem exactly, we will reason about whether constant factor approximation algorithms exist, i.e. TOP 30 IMPORTANT QUESTION OF Design & Analysis of Algorithm(DAA) For GBTU/MMTU C.S./I.T. 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. Due to the connection between approximation algorithms and computational optimization problems, reductions which preserve approximation in some respect are for this subject preferred than the usual Turing and Karp reductions. Explain NP-Complete and NP- Hard problem. If one can establish a problem as NP-complete, there is strong reason to believe that it is intractable. My answer is that is it ignores randomized and approximation algorithms. Approximation algorithm: identifies approximate solutions to problems (mostly often NP-complete and NP-hard problems) to a certain bound. Note that hardness relations are always with respect to some reduction.
