I hope I'm addressing the right community. For a project for my students, I need to find some weighted graphs (oriented or not) to benchmark their algorithms (shortest paths, flows...).
There are a few samples on the companion site of the ALGS4 course from R. Sedgewick (Shortest Paths), but I would like some more datas, encoded in this simplest way (or easily convertible).
Maybe someone here is aware of some samples and could point me to it.
Thanks in advance.
