WebSep 28, 2024 · With Dijkstra's Algorithm, you can find the shortest path between nodes in a graph. Particularly, you can find the shortest path from a node (called the "source node") to all other nodes in the graph, producing a shortest-path tree. This algorithm is used in GPS devices to find the shortest path between the current location and the destination.

WebOct 18, 2024 · Train line in this case means a train that goes from a starting station to a ending station, with many station stops on the way, where certain station stops may give the option for the rider to swap to another "line" that also has its starting and stoping station. A simple example is a two-line subway system like so:
