TOP 30 IMPORTANT QUESTION OF Design & Analysis of Algorithm(DAA) For GBTU/MMTU C.S./I.T. To minimum spanning trees and Huffman codes; dynamic programming, including applications to sequence alignment and shortest-path problems; and exact and approximate algorithms for NP-complete problems. Algorithms vis-à-vis Everyday Programming; Polynomial-Time Algorithms; NP-Complete Problems. Also Discuss What is meant by P(n)-approximation algorithm? 12.3 approximation algorithms for np-hard problems 441. This problem addresses the issue of timing when deploying viral campaigns. 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. The Travelling-Salesman; Subset-Sum; Set-Covering. Approximation algorithms for the knapsack problem 453. Explain NP-Complete and NP- Hard problem. In 2003 proved that it is still NP-hard and gave a polynomial-time algorithm with an approximation factor of 1nm. Both these problems are NP-hard, which motivates our interest in their approximation. Presented at Computer Science Department, Sharif University of Technology (Optimization Seminar ). Approximation algorithms for the traveling salesman problem 443. This problem is known to be NP-hard even for alphabet of size 2. Problem classes P, NP, NP-hard and NP-complete, deterministic and nondeterministic polynomial time algorithms., Approximation algorithms for some NP complete problems. Since many interesting optimization problems are computationally intractable (NP-Hard), we resort to designing approximation algorithms which provably output good solutions. It is known that the decisional subset-sum is NP-complete (I believe this result is essentially due to Karp). I still maintain that someone could make a good movie with the premise "random guy finds easy algorithm to solve NP-complete problems now what?" in the vein of Primer (random guys . There are already arbitrarily good polynomial-time approximation algorithms for many NPO-complete problems like TSP, but TSP is actually APX-complete too, meaning you cannot even approximate answers beyond a certain factor unless P=NP.
