Shortest path is a fundamental graph problem with numerous a pplications. However, the concept of classic shortest path i s insufficient or even flawed in a temporal graph, as the temporal info rmation determines the order of activities along any path. In this paper, we show the shortcomings of classic shortest path in a temporal graph, and study various concepts of “shortest” path f or temporal graphs. Computing these temporal paths is challengin g as subpaths of a “shortest” path may not be… CONTINUE READING
