Details for the issue

What did you do?

Use a variable with the name 'b' with the solver GLPK_CMD

What did you expect to see?

When submitting an instance that has no time_window key for vehicles and time_windows key for any of the tasks, then it's treated as a CVRP which removes the need for all time validity checks. So far so good. But this behavior remains if a vehicle has a non-empty breaks array. Then the result of the problem being treated as a CVRP is that the breaks are not assigned at all.

One may argue

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
