  • Woah, neat. Is this like, a Markov chain?

  • 46 and that was my ceiling. frogs smarter than me.

  • plot twist: there is no frog, it's all your internal biases (what you do after success/failure)

  • Curious how a couple people got >100 hits on 100 punches

  • some people went on to explore the code limits, hehe. it's been fixed

  • Would be fairer if the frog occasionally got to throw a punch or two...

  • On my todo list: when the frog wins, it runs towards you and knocks you out, haha

  • In the first round I struggled to notice if I missed. The frog punching back would be a good indicator. And I wouldn't feel so guilty for punching a pacifist frog.

  • That was fun, got up to 79 :)

  • I once coded a rock-paper-scissors game that you can play against a tree based matcher/learner, with symmetry between the options accounted for. Pretty similar idea-wise. To be honest, it was pretty hard to get a better than random score.

  • If you want to see what a random distribution looks like:

      jot -r 100 0 1 | rs -t 10
    I noticed my "fake randomness" is lacking long sequences of the same key. I feel like I'm "predictable" when I press the same key 5 times in a row, yet that happens a lot in a truly random distribution.

  • With Brain Frog I went even further - it doesn't actually check L/R. Instead, it checks what you do after a landed/blocked punch (some people tend to switch after a block, others insist on hitting the same side until they land a hit).

  • what's your score?

  • The ultimate unpredictability.

  • You should make one where you can play against the branch predictors of various processors.
    by mike_hock
  • I was just about to comment the same! Sadly, branch predictors are incredibly well guarded secrets, mostly.

  • pure random player:

      (async function(punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      punch(['L', 'R'][(Math.random() * 2) | 0])
      await sleep(delay)
    }
  })(punch, 150)
    "cheating" player:

      (async function(oracle, punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      punch((i + 1) < oracle.minForPrediction ? ['L', 'R'][(Math.random() * 2) | 0] : oracle.predictNextPunch() === 'L' ? 'R' : 'L')
      
      await sleep(delay)
    }
  })(oracle, punch, 150)
    is it possible to do any better? i haven't fully read frog/oracle code
    by escanor
  • it is:

      (async function(oracle, punch, delay) {
    async function sleep(ms) {
      return new Promise((resolve, _) => {
        setTimeout(resolve, ms)
      })
    }
    
    for (let i = 0; i < 100; i++) {
      const state = oracle._state
      const block = oracle.predictNextPunch()
      oracle._state = state
      
      punch(block === 'L' ? 'R' : 'L')
      
      await sleep(delay)
    }
  })(oracle, punch, 150)
    by escanor
  • Less fancy hack here, intercept the prediction function on every punch and force the frog to take the opposite side. const realPunch = punch;

    punch = function(myMove) {

      oracle.predictNextPunch = function() {
    return myMove === 'L' ? 'R' : 'L'; 
  };
  
  realPunch(myMove);
    };

  • I got 50 hits in 100 tries. That being said, I did not particularly like hitting that poor frog :'( Yes, I am the kind of player who would never choose the rude option when talking to an NPC.
