Ragdoll is the technology of making the CG animated characters to act like a dummy in the scene. The advantage is for example if you hit a character with a gun like in the game Counter Strike Source, the character you've been hit will fall down or basically a dummy when hit (you know what I'm saying).
Euphoria is more advance than ragdoll physics is more one of kind dummy with brains, you know what that means? It has it's own movements and reacts faster to the enviroment in short AI(Artificial Intelligence) is present.
One big breakthrough for game developers and animators in Animation, because DMS (Dynamic Motion Synthesis) technology is here. And making each character animation comes to realistic movements. No more hustle coding each movements, key-frame animation and motion animation.
