Claudico
- Claudico** is an artificial-intelligence computer-program designed to play no-limit Texas hold 'em heads-up.
History Claudico was designed by Carnegie Mellon professor tuomas-sandholm and his graduate students. The name means "I limp" in Latin, a reference to limping into a hand without raising—a strategy the bot employs often. For each 750-hand set, the same hands were dealt to one human taking on Claudico on the main casino floor and another battling the computer in an isolation room, with the hole cards reversed. This was done to ensure that card luck was not a factor in the outcome. The 80,000-hand sample represented the largest-ever human–computer data set. Claudico was able to adjust to its opponent's strategy as the matches progressed, just as the humans could. Additionally, the matches were broadcast online via Twitch.
The blinds were 50 and 100 chips for every hand, and both the human's and computer's chip stack were reset to 20,000 at the beginning of each hand. Halfway through the match, the human team was ahead 458,000 chips versus Claudico. The humans went on to increase their lead, winning the match by 732,713 chips. Polk finished up 213,000, Li won 529,000, Kim beat Claudico by 70,000, and Les finished down 80,000. A total of 170 million chips were bet over the 80,000 hands. Polk said Claudico had played well in spots, but also made some bad plays. Overall, it played very differently than humans. "Where a human might place a bet worth half or three-quarters of the pot, Claudico would sometimes bet a miserly 10 percent or an over-the-top 1,000 percent", he explained. "Betting $19,000 to win a $700 pot just isn't something that a person would do".
