WebDec 27, 2024 · Greedy Algorithm. Although all the heuristics here cannot guarantee an optimal solution, greedy algorithms are known to be especially sub-optimal for the TSP. 2: Nearest Neighbor. The nearest neighbor heuristic is another greedy algorithm, or what some may call naive. It starts at one city and connects with the closest unvisited city. Webity on the search heuristic may be studied by running the heuristic on all graphs in the collection. Given this objective, the rst step is to identify graphs with extremal assortativity within the class. This paper examines two greedy heuris-tics for nding maximum assortative graphs within a class: graph rewiring and wiring. 1.2.
