https://github.com/Pyomo/pyomo supports AMPL, PICO, CBC, CPLEX, IPOPT, Gurobi and GLPK.
What about osqp? I'm lacking any knowledge about how interchangeable it is.

## Summary
Ran pyomo solve to optimize a model with one set of binary variables, using gurobi. The optimization was fine, but print(results) showed negative 'number of continuous variables'

Details for the issue
--------------------
#### What did you do?
Ran pulp using the GUROBI solver and set a time limit.
#### What did you expect to see?
After time limit hit, the best inc…

Right now, adding callbacks throws an error. For example:
```
using JuMP, BilevelJuMP, Gurobi
model = BilevelModel(Gurobi.Optimizer, mode = BilevelJuMP.SOS1Mode())
@variable(Lower(model), x)
…

I noticed this over at https://trac.sagemath.org/ticket/29955, but that ticket is not necessary to expose the problem. Basically, the `__repr__` output changes when this package is installed.
First…

My PC (win 11) only installed Gurobi 10.0.1 and my license is for version 10. But every time when I used gurobi in JuMP and wrote out the logfile, JuMP is using Gurobi 11.0.2 as follows,
Is it on…

While we're adding to the MathematicalProgram wishlist, it would be nice to be able to read the active set of inequality constraints at optimality. This may be difficult to do in a generic way, since …

The current version of `GLPKMathProgInterface 0.1.11` might have an issue regarding problem modification. In a Benders decomposition problem using `JuMP`, after the callback function adds a lazy cons…

Description:
I am working on a problem where I need to create constraints with a right-hand side that has two indices, as shown in the following formulation:
$$
\sum_j c_j y_{ij} \le b_{ij} \qu…

I'm experiencing a problem where I run the same model multiple times, but I get different solving paths for same solver each time. Even though the objective function values are the same, the decision …
