[Fix] AliG optimizer visualization + Some plots showing optimizer vars

[AidinHamedi]

Problem (Why?)

execute_steps in examples/visualize_optimizers.py will modify optimizer_config for some optimizers with unique requirements and that will cause the modification of the original best_params var and that will cause the next function plot_function show invalid information.

Solution (What/How?)

Make a copy of the best_params before giving it to execute_steps to mitigate the modification of the original var.
