Find Shortest Path in Graph, Dijkstra Algorithm

Web26 jul. 2013 · igraph does not check whether the graph is a DAG before running any shortest path related function. Yes, shortest paths can be found faster in a DAG but this use-case is so rare that no one bothered to implement the special case so far. Custom code written in pure Python is likely to be slower than a C implementation, but it depends ...
