How to introduce customized stop criteria

[AmirShahbazi90]

I could not find any argument in this package to introduce my own stop criteria in gp_minimize().

for example if difference between 2 successive evaluations of my objective function is less than 1e(-6) it is fine and no longer I need further evaluations.
I am looking forward to implement my Hyperparameter optimization in the way and also access the number of evaluations at which my stop criteria is in effect.

Is there any possibility to do so with this function(gp_minimize())?

Seems what you are looking for is skopt.callbacks.DeltaYStopper.
