Hi @michaelbynum . When we are using a persistent solver in Pyomo, we can get the native solver object through `self._solver_model`. However, in `appsi_cplex`, it's named `self._cplex_model`. Will this be...

One more thing. I just found that in `appsi_gurobi`, `_pyomo_var_to_solver_var_map` is a `dict()` and uses variable id as the key. In `gurobi_persistent`, `_pyomo_var_to_solver_var_map` is a `ComponentMap` and uses variable as...

In MindtPy, there are two occasions that use `_pyomo_var_to_solver_var_map`. The first one is the single tree implementation of Outer Approximation method, which need to access the incumbent solution during the...

Hi @jsiirola and @ghackebeil . Recently, I need to use SCIP in Pyomo and find this issue. Is there any progress with the SCIP interface or `scip_persistent` in Pyomo? Thanks.

Excellent work!

Hi Alex. Currently, MindtPy does not support `pyomo.kernel` models. If you want to use MindtPy, you need to build your model in `pyomo.environ`.

Thanks. @jsiirola @michaelbynum

I have one question here. If the coefficient of linear terms is `native_numeric_types`, why would the accumulation become so complicated? like `expr -= - c*v`. https://github.com/Pyomo/pyomo/blob/5683dc3d46e6c4a3a675624f23b0c14d6578be1a/pyomo/repn/standard_repn.py#L180-L188

I checked again. Multi threads are used when building `pyomo` models. More exactly, this line. ```module = import_module("unitcommit_200_100_2_mod_7")```

Hi @emma58 . Sorry for the late reply. I did benchmark tests for MindtPy this week. Plenty of problems fail due to this change. - Imagine that there is a...
