WebTraveling Salesperson Problem: TSP is a problem that tries to find a tour of minimum cost that visits every city once. In this visualization, it is assumed that the underlying graph is a complete graph with (near-)metric distance (meaning the distance function satisfies the triangle inequality) by taking the distance of two points and round it to the nearest integer.

TSP can be modelled as an undirected weighted graph, such that cities are the graph's vertices, paths are the graph's edges, and a path's distance is the edge's weight. It is a minimization problem starting and finishing at a specified vertex after having visited each other vertex exactly once. Often, the model is a complete graph (i.e., each pair of vertices is connected by an edge). If no path exists bet… WebDefinitions Tree. A tree is an undirected graph G that satisfies any of the following equivalent conditions: . G is connected and acyclic (contains no cycles).; G is acyclic, and a simple cycle is formed if any edge is added to G.; G is connected, but would become disconnected if any single edge is removed from G.; G is connected and the 3-vertex …
