My answer is that is it ignores randomized and approximation algorithms. In this problem, multiple missions compete for sensor resources. The computer scientist Richard Karp, of the University of California at Berkeley, showed that the traveling salesman problem is “NP-hard,” which means that it has no efficient algorithm (unless a famous conjecture called P=NP is true — but the majority of computer scientists now suspect that it is false). I'm enjoying reading notes from Shuchi Chawla's course at the University of Wisconsin, Madison on approximation algorithms for NP-hard optimization problems. The problem is NP-hard and an approximation algorithm has been described in the reference. We show both problems to be NP-hard and prove limits on approximation for both problems. 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. They showed that this problem is NP-hard even to approximate, and presented several heuristic algorithms. An infinitesimal advance in the traveling salesman problem breathes new life into the search for improved approximate solutions. Problem classes P, NP, NP-hard and NP-complete, deterministic and nondeterministic polynomial time algorithms., Approximation algorithms for some NP complete problems. We present integer programs for both GOPs that provide exact solutions.
