We are going to use the Manhattan Distance as the heuristic function in this tutorial. The Greedy algorithm starts from a node (initial state), and in each step, chooses the node with the minimum heuristic value, which is the most promising for the optimum solution.

This statement says that there are known instances of TSP (that is, specific graphs with weights on them) where the ratio NN(I) / OPT(I) is Θ(log n) (that is, the ratio is proportional to the log of the number of nodes in the graph). Because we already know about inputs like this, there's ...
WebThe article you linked to deals with the asymmetric travelling salesman problem. The authors have a subsequent paper which deals with the more usual symmetric TSP: Gutin and Yeo, "The Greedy Algorithm for the Symmetric TSP" (2007).An explicit construction of a graph on which "the greedy algorithm produces the unique worst tour" is given in the proof of … WebNov 27, 2024 · The heuristic is a more complex greedy TSP heuristic where all edges of the graph are sorted from shortest to longest. Edges are then added to the tour starting with the shortest edge as long as the addition of this edge will not make it impossible to complete a tour. Specifically, this means avoiding adding edges that make early cycles, and ...
