What a great resource! The first example is perfect:
> Aircraft landing
> Evolved algorithm for landing aircraft exploited overflow errors in the physics simulator by creating large forces that were estimated to be zero, resulting in a perfect score
> In an artificial life simulation where survival required energy but giving birth had no energy cost, one species evolved a sedentary lifestyle that consisted mostly of mating in order to produce new children which could be eaten (or used as mates to produce more edible children).
> (Tetris) Agent pauses the game indefinitely to avoid losing
>Agent kills itself at the end of level 1 to avoid losing in level
>Robot hand pretending to grasp an object by moving between the camera and the object
