First I want to thank the Authors that they implemented cuOpt API in Julia. I also wish to encourage to bundle cuOpt_jll so that installation is easier.
I would like to solve VRP’s with cuOpt, but the documentation only shows how to use cuOpt with JuMP. It does not mention VRP presets. Can VRPs be solved with its Julia API or if not is it planned?
so that installation is easier
You could try the Colab instructions. Download via pip: GitHub - jump-dev/cuOpt.jl: A Julia interface to NVIDIA's cuOpt
Can VRPs be solved with its Julia API
Nope
or if not is it planned?
Not by any of the JuMP folks. Is there are a C API for the VRP solver?
Alternatively: take a look at Hexaly or OR-Tools.
Thank you. There is no C API for VRP solver for now.
Feel free to open an issue if that ever changes. But there’s nothing we can do on our end before then
