Japanese Researchers Build Rock-paper-scissors Robot That Wins 100% of the Time

slew writes "Although the robot technically cheats because it watches your hand and can recognize what shape you are intending to make and beat it before you even know what is happening. Apparently it takes about 60ms for you to shape your hand, but the robot can recognize the shape before it is completed, and only takes 20ms to counter your shape so the results appear to the human opponent to be virtually simultaneous. I wonder how difficult it would be to add lizard and spock to the mix.... ;^)."

I dutifully flagged this as a dupe in the firehose before it made it to the front page. Lot of good it did!

Sounds like the halting problem

Have it play against itself, then we'll see some small values of 100%.

It won't complete the first round, as both will just sit there waiting for the other to move. "Never loses" might be the best way of describing it.
