May be you mean APSP = all pairs shortest path
In your case:
- get rid of all uneven numbered edges
- reverse the remaining edges
- compute APSP, where addition is replaced by concatnation
- de
Nothing important, just something I'm curious about:
At least a couple times recently I've come across a certain pattern for
dealing with directed graphs (ones that may have cycles). It seems general
enough that I'm surprised I don't seem to recognize it (but then again, it
has been years since
