AI specific RTS Game Engine

[shakeel]

Hi,

I am working on a RTS game working on an idea but i will mainly focus on AI techniques as a Computer Science student. I need suggestions about any free RTS game engine best suited to implement AI. I have gone through some of them but i want to know from your side may be it is more helpful. I also need that one which will take less time to learn how to use it.
