"use_branching_in_lp" parameter in v9.9

[IgnaceBleukx]

Hi,

I am doing some hyperparameter tuning for the CP-SAT solver for some of the models I got.
Version 9.8 had the parameter use_branching_in_lp Boolean parameter, but it seems to be removed in v9.9.
Is there a way to still turn on/off the branching? Or is the parameter just renamed?

Kind regards,
Ignace

It was removed.
We had zero worker using it.

I recommend using multiple workers as it does a good job at having diverse strategies.
Otherwise, you can have a look at https://github.com/google/or-tools/blob/stable/ortools/sat/cp_model_search.cc#L649
