solver

Describe the new feature

Can we have support for the new, but promising HiGHS solver?

Additional info

Does this feature exist in another product or project? Please provide a link.

Julia language supports using HiGHS from within JuMP modelling language.

Thanks,
Sam

With v1.9.0, it used to be possible to provide a custom matrix and yet use calls to a routing engine to get additional information, namely geometry and distance values.

As of v1.10.0, this results in an error:

$vroom -i input_with_custom_matrix.json -g
[Error] Route geometry request with non-routable profile car.

It would be nice if Choco were able to support MiniZinc output format.

Hi! I am very new to Rust, so I apologize if this ends up being a naive question.

So, for my robot motion optimization application, I have created an objective function and gradient function in the required format using closures, but the closure types are FnMut’s rather than Fn’s. This leads to the compiler complaining since the OpEn library forces the objective and gradient functions to be F
