Minimax or Maximin? – Becoming Human: Artificial Intelligence Magazine

Minimax, as the name suggest, is a method in decision theory for minimizing the maximum loss. Alternatively, it can be thought of as maximizing the minimum gain, which is also know as Maximin. It all started from a two player zero-sum game theory, covering both the cases where players take alternate moves and those where they made simultaneous moves. It has also been extended to more complex games and to general decision making in the presence of uncertainty. In the above explanation, it has been mentioned that the minimax algorithms started off with the concept of zero-sum.
