Approximation Algorithms for NP-Hard Problems Dorit Hochbaum
Publisher: Course Technology




The traveling salesman problem (TSP) is an NP-complete problem. This book deals with designing polynomial time approximation algorithms for NP-hard optimization problems. In this problem, multiple missions compete for sensor resources. The Hitting Set problem is NP-hard [Karp' 72]. We present integer programs for both GOPs that provide exact solutions. (So to solve an instance of the Hitting Set Problem, it suffices to solve the instance of your problem with. We show both problems to be NP-hard and prove limits on approximation for both problems. Different approximation algorithms have their advantages and disadvantages. Comparing Algorithms for the Traveling Salesman Problem. They showed that this problem is NP-hard even to approximate, and presented several heuristic algorithms.
