Re: [scikit-learn] Any way to tune the parameters better than GridSearchCV?

I would like to make a related suggestion but instead of focusing on the upper bound for the number of trees rather set choosing the lower bound. From a theoretical perspective, it doesn't make sense to me how fewer trees can result in a better performing random forest model in terms of generali

Take random forest as example, if I give estimator from 10 to 1(10, 100, 1000, 1) into grid search. Based on the result, I found estimator=100 is the best, but I don't know lower or greater than 100 is better. How should I decide? brute force or any tools better than GridSearchCV? thx __
