Consider A->B and A->C->B as paths from A to B in a graph. BFS will say that after going along one of the path that B is visited. When continuing to travel the next path it will say that marked node B has been again found,hence, a cycle is there. Clearly there is no cycle here. Share

WebGPS navigation implementation; Breadth-First Search (BFS) There are differences in the route which I usually take and the one which GPS shows as the shortest, probably due to the algorithms used. I learned from my graph theory data structure classes that Breadth-first search is used in GPS and digital maps.
