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

[lampahome]

Take random forest as example, if I give estimator from 10 to 10000(10,
100, 1000, 10000) 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
