Traveling Salesmen Problem heuristics @ Fast operations such as 2-Opt are less computationally expensive, but due to granularity, more likely to become stuck in local extrema. Local search w i t h k-change neighborhoods is perhaps the oldest and most widely used heuristic method for the traveling salesman problem, yet almost no theoretical performance guarantees for it were previously known. It is also called a tour improvement algorithm. x1, x2, x3 are replaced by y1, y2, y3 The algorithm is specified in exchanges (or moves) that can convert one candidate solution into another. This is known as the k k -Opt algorithm.
