You vs. the Computer in Rock-Paper-Scissors



Over at the website for The New York Times, they have added a rock-paper-scissors game where you play against a computer, which is getting better and better at predicting what your next move will be.


Computers mimic human reasoning by building on simple rules and statistical averages. Test your strategy against the computer in this rock-paper-scissors game illustrating basic artificial intelligence. Choose from two different modes: novice, where the computer learns to play from scratch, and veteran, where the computer pits over 200,000 rounds of previous experience against you.

I played about 30 times. After the about the first 15 I started to lose a lot more because its knowledge of my moves started to grow rapidly. If you choose to see what the computer is thinking, it is really interesting to follow its thought process.

I played the expert and used a random number generator so no human thought process strategy. The score was me 4 wins, computer 6 wins and the 5 ties.

After 16 rounds I gained on the "Veteran" computer.

Wins: 5
Ties: 7
Losses: 4

But I've also studied human and artificial intelligence on the cellular and programming level. I learned to predict what the computer would do, based on its rules for predicting what I would do. I'd throw rock a couple of times, then, anticipate the computer would choose paper, but also that the computer would anticipate me choosing scissors based on it's experience and so I'd choose paper assuming it would choose rock to try to beat my scissors. Seems to have worked somewhat.

I managed 6w 14t 4l. Novice is easier to game in the short term but I think expert will be easier in the long term if you know a bit about human behaviour.
