      • ‘Michie recalls Turing experimenting with heuristics that later became common in chess programming (in particular minimax and best-first).’
      • ‘This paper introduced the idea of minimax reasoning for lower bounding randomized algorithms, and appeared only in FOCS 83.’
    2. 1.2as modifier Denoting the theory that in a game with two players, a player's smallest possible maximum loss is equal to the same player's greatest possible minimum gain.
      • ‘In game theory von Neumann proved the minimax theorem.’
      • ‘One possible solution is the minimax search algorithm.’
