TSP is a famous NP hard (non-polynomial) problem. The issue isn't that we don't know a solution to it, but that all solution are O (N!) complexity. Lots of algorithms do many smart things to cut down on obviously bad solutions but worst case (complete graph with equals weights) will run in O (N!). Dijkstra is a polynomial algorithm. chrysler 300 car dealer near surprise
