Thanks, that does exactly what I needed! It is significantly faster and uses significantly less memory. --Beth On Wednesday, August 25, 2021 at 6:33:36 AM UTC-5 Jean-Florent Raymond wrote: > Hello, > > The function shortest_simple_paths returns an iterator with paths sorted > by increasing len

Hi, I release cocalc-docker ([1], [2]) a few days ago with sage-9.4, and had people reporting back "illegal instruction" issues. Sage is built there with SAGE_FAT_BINARY="yes", using this script [3]. One person who reported a problem had a "Dell PowerEdge R710." and I built on an intel Dell

Hello, The function shortest_simple_paths returns an iterator with paths sorted by increasing length. Therefore if you only want paths of minimum length, you can iterate over the result of shortest_simple_paths and stop as soon as you encounter a longer path. That way you do not iterate over all t
