-### 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)
-```
