Heuristic Approaches
By using approaches based on heuristics, practical applications of TSP can be solved since the optimal solution is not always needed. By using heuristics, sub-optimal solutions can be found, and often times just having a solution is “good enough”. Random Optimizations Optimised Markov chain algorithms which utilise local searching heuristically sub-algorithms can find a route extremely close to the optimal route for 700-800 cities. Local Search Start off with a valid tour, then use local moves to improve the tour. Terminates at a “local minimum.” Nearest Neighbor Start at a node, and selected the nearest unvisited node; repeat until done. Worst case creates a complexity of ½ log n. Greedy Algorithm Start with empty partial tour. Add smallest edge that results in a valid partial tour. Repeat until complete tour reached. Worst case creates a complexity of ½ log n.
