### Selecting the internal MIP solver
|
|
|
|
By default, `LearningSolver` uses [Gurobi](https://www.gurobi.com/) as its internal MIP solver. Alternative solvers can be specified through the `internal_solver_factory` constructor argument. This argument should provide a function (with no arguments) that constructs, configures and returns the desired solver. To select CPLEX, for example:
|
|
```python
|
|
from miplearn import LearningSolver
|
|
import pyomo.environ as pe
|
|
|
|
def cplex_factory():
|
|
cplex = pe.SolverFactory("cplex")
|
|
cplex.options["threads"] = 4
|
|
return cplex
|
|
|
|
solver = LearningSolver(internal_solver_factory=cplex_factory)
|
|
```
