WebSep 6, 2024 · The Traveling Salesman Problem. One especially important use-case for Ant Colony Optimization (ACO from now on) algorithms is solving the Traveling Salesman Problem (TSP). This problem is defined as follows: Given a complete graph G with weighted edges, find the minimum weight Hamiltonian cycle. That is, a cycle that passes through … WebMay 1, 2024 · In this article we will restrict attention to TSPs in which cities are on a plane and a path (edge) exists between each pair of cities (i.e., the TSP graph is completely connected).
