Hi,
I am implementing a Benders decomposition. I hope to build the master problem use `copy_model` with `filter_constraints`, but the `lower_bound` is not copied to the new model.

## Summary
Currently in **APPSI**, if the problem is infeasible and `config.load_solution=True`, a `RuntimeError` will be raised.
For example, in **appsi/solvers/cplex.py**, there are several pla…

**Describe the bug & Expected behavior**
I'm not sure how the decomposition work with benders, but here, I expect the `d` variable to be the (unconstrained) master problem. There is two subproblems `…

Hi,
I've got two issues while using Xpansion :
1. I am working with two different studies. On the first one, Xpansion is working, but in the second one, when i am doing the exact same methodolog…

Hi,
I want to implement Benders Decomposition Algorithm to my problem. First, I just wanted to code the algorithm by myself using dual values, but there are "bound constraints" in my problem. Dual…
