This is interesting, i first thought I can use all 4 arrow keys, so i tried to make random movements with 4 keys.
The program only guessed 49% of my inputs right over 100 Iterations.
When I understood it's only two keys the program guessed correct 60% of the time.
- kannanvijayan 8y agoThe (napkin-sketch) model of that behaviour is interesting. I'd guess that when you are pressing 4 buttons, your "internal pseudo-RNG" is incorporating a broader scope for entropy that isn't visible to the algorithm which only "sees" the two horizontal arrows. Incidentally, I also got about the same rate (59%) of success from the algorithm when I used only the two recognized keys.
- penagwin 8y agoI just tried this out, using all 4 arrow keys lands me around 52%, just the two is 60% like you guys. This is kinda cool, our brain's RNG does better with more "mental outputs"...
- pbhjpbhj 8y agoIf you imagine you're pressing one of 4 keys and then collapse the key choice as a projection on to two keys then do you get closer to the original 4-key randomness?
- dTal 8y agoSame result. 50% with four keys, 60% with just the two. This is very interesting...
