Robot Hand Beats You At Rock, Paper, Scissors 100% of the Time

Posted by Soulskill on from the we-have-outlived-our-usefulness-as-a-species dept.

wasimkadak writes "This robot hand will play a game of rock, paper, scissors with you. Sounds like fun, right? Not so much, because this particular robot wins every. Single. Time. It only takes a single millisecond for the robot to recognize what shape your hand is in, and just a few more for it to make the shape that beats you, but it all happens so fast that it's more or less impossible to tell that the robot is waiting until you commit yourself before it makes its move, allowing it to win 100% of the time."

    So it cheats.

      I think it's probably inspired by recent research that showed unambiguously that people who are good at janken/rock-paper-scissors achieve their success by throwing as late as possible, observing the opponent's hand to see what gesture is going to be made.
      Talk about reading people's faces / moods / history is mostly bullshit. Although computer software tends to abuse our human non-randomness in this way, it is in practice intractable for most humans. And the best janken players rely solely on the same strategy this robot's using.
      But then, if you didn't want to be cheated, you shouldn't play a game where cheating is pretty much the only way to consistently win.

      That's the only way to win a game of chance 100% of the time...

      If it really is a game of chance then there is a possibility that someone will win it 100% of the time.

      One round of RPS is one set of throws to a winning result. In other words, for a single round, you will have a single winner. Since the win can't be split (a tie thrown out and the competitors re-throw), After that one round, 1 of the people will have won 100% of the rounds. Exactly as the person you responded to stated.

    When your opponent loses, his next move will be to beat whatever your move was on that round.

    I'm sorry to say that, but you must have been playing really dumb people.
