Not only it is important to define and balance strategies, but also the results of keeping track of the opponent's actions. That's why we need to implement a member function for adding them into the mix we talked about in the previous section:
public void TellOpponentActionRM(RPSAction action){ lastOpponentAction = action; int i; for (i = 0; i < numActions; i++) { regret[i] += GetUtility((RPSAction)lastActionRM[i], (RPSAction)action); regret[i] -= GetUtility((RPSAction)lastAction, (RPSAction) action); }}
Finally, it's important to balance the strategies and the utility function. It's pretty straightforward for RPS, but it could get as complex as our game.
