Note that hardness relations are always with respect to some reduction. I normally do machine learning work, and when I'm evaluating an algorithm on a data set, I always use cross-validation to determine how effective the. Approximation Algorithm vs Heuristic. In 2003 proved that it is still NP-hard and gave a polynomial-time algorithm with an approximation factor of 1nm. The theory of NP-completeness suggests that some problems in CS are inherently hard—that is, there is likely no possible algorithm that can efficiently solve them. The Travelling-Salesman; Subset-Sum; Set-Covering. Since many interesting optimization problems are computationally intractable (NP-Hard), we resort to designing approximation algorithms which provably output good solutions. 12.3 approximation algorithms for np-hard problems 441. 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. Algorithms vis-à-vis Everyday Programming; Polynomial-Time Algorithms; NP-Complete Problems. Presented at Computer Science Department, Sharif University of Technology (Optimization Seminar ). Approximation algorithm: identifies approximate solutions to problems (mostly often NP-complete and NP-hard problems) to a certain bound. When an NP-complete problem must be solved, one approach is to use a polynomial algorithm to approximate the solution; the answer thus obtained will not necessarily be optimal but will be reasonably close. Often, when dealing with the class NPO, one is interested in optimization problems for which the decision versions are NP-hard. Also Discuss What is meant by P(n)-approximation algorithm?
