Man vs. A.I. machine in Texas Hold'em matchup

In this 'epic rematch,' artificial intelligence system will be tested

The new program, Libratus, was built from the ground up, using new ideas and more computation than any other pokerbot, according to Sandholm.

Sandholm, who worked on the new program with his Ph.D. student Noam Brown, said they have been using the Bridges supercomputer at the Pittsburgh Supercomputing Center to calculate what they hope will be winning strategies.

"We don't write the strategy," Sandholm said. "We write the algorithm that computes the strategy."

"We're pushing on the supercomputer like crazy," Sandholm said. About 15 million core hours of computation were used to build Libratus, compared with the 2 million to 3 million core hours for Claudico. That computing process will continue up to and during the contest.

Brains vs. A.I. is sponsored by GreatPoint Ventures, Avenue4Analytics, TNG Technology Consulting GmbH, the journal Artificial Intelligence, Intel and Optimized Markets, Inc.

Most of the $200,000 prize purse came from the sponsors, though the casino and the CMU School of Computer Science also contributed.
