Hi, @mewilhel, this issue follows the previous one #3, but I think it is more appropriate to open two issues.
I am new to McCormick relaxation and learn the basics from the paper [1], especially th…

Right now, we're using a fancy overloading approach to build relaxations of nonlinear terms. Expansiveness of the interval calculations can lead to intermediate terms containing an interval bound on w…

Hi, I encounter the same problem as in https://github.com/facebookresearch/LAMA/issues/10.
And I found the reason why 2 examples are filtered is that the `obj_label` are `1970s` and `1990s`. And in `…

Hi all,
It'd be great to have a constructor for `MC` which takes just the `cv`, `cc`, and `Intv` arguments, for situations where we don't know or care about subgradients. This specific constructor …

I am a summer undergraduate research assistant working with Dr. Kamil Khan. We found that the concave relaxation of `exp(x::MC)` seems to be computed as `NaN` when x is degenerate. Presumably this is …

This issue is to keep track of the planned refactor and new features for Alpine.jl . To complete this refactor, the following things need to be taken care of. This can be…

In the attached mps file, column 28 is clearly constrained to be equal to zero on row 29. However, after reading and solving this file, the column solution gives a value of 1.0000000000000007.

## Summary
I'm trying to solve a simple integer non-linear problem using MindtPy, but the solutions returned are far from optimal (Gurobi does find the optimum correctly).
### Steps to reproduce…
