WebApr 3, 2012 · Shortest path from A to B is via C. Now add constant 2 to all edges. The shortest path becomes instead the single step from A directly to B (owing to "penalty" we've introduced for using additional edges). Note that the number of edges used is (excluding the node you start from) the same as the number of nodes visited. WebCommon graph algorithms include traversing a graph and computing the shortest path between nodes. Implementing these algorithms is a great way to learn how graphs are …
