How to evolve based on head to head battles?

[travis-leith]

If I want to evolve organisms that compete in head to head 2 player contests (like tic tac toe), is there any guidence on how to set this up. An example would be great. I note that the test function for the Environment trait has a parameter for only a single organism. Is there a convenient way to set up 2 player games?

I never test it, but I think you can create an environment where you can identify the player by a variable, and change it before call evaluate_it method for one and other player in the same loop. The environment can asign this movement to actual player selected.
