Hi AbruptWorm50

I was wondering if it possible to specify 'patience' of pruning algorithm?

Any of the kwargs passed to **optimizer_kwargs will be directly passed to the optuna obejct

It should allow you to control the parameters, no?

Regrading the callback, what exactly do you think to put there?
Is the callback this enough?
