TSP Algorithms and heuristics. Although we haven’t been able to quickly find optimal solutions to NP problems like the Traveling Salesman Problem, "good-enough" solutions to NP problems can be quickly found [1].. For the visual learners, here’s an animated collection of some well-known heuristics and algorithms in action.

A → B → D → C → A. Cost of the tour. = 10 + 25 + 30 + 15. = 80 units. In this article, we will discuss how to solve travelling salesman problem using branch and bound approach with example. Deleting arcs (7,8) and (10, 9) flips the subpath from 8 to 10. Two TSP tours are called 3-adjacent if one can be obtained from the other by deleting three edges and adding three edges. 3-opt heuristic. Look for a 3-adjacent tour with lower cost than the current tour. If one is found, then it replaces the current tour.
