Hi all,
Could you give me an example of how I could run several optimizations using different optimization parameters ('cp_model_probing_level', 'linearization_level', 'symmetry_level', 'search_branching') ?

Many thanks in advance.

Is there any answer different than just running different separate processes ?

No you're right.

But what the syntax to run the solver with different values of the above listed parameters ?

Any thoughts ?
