Robots vs Best Players: Zenith and Aralık's Stars & Platinum Event

This month, we set out to evaluate the capabilities of the various bridge robots used or developed on BBO. To do this we expanded our usual robot simulations, where BBO's GIB robots compete against real players in daylong games, to include two highly competitive events: Aralık's Stars and Platinum Robot Individual, and one of BBO's Zenith Daylongs.

In the first simulation, five different robots replayed the Aralık Stars & Platinum Robot Individual to assess their performance against human players. The participating robots were:

  1. GIB Advanced
  2. GIB Basic
  3. Argine Advanced
  4. Argine Basic
  5. "ACBL-Ben", a variant of Lorand Dali's "Ben" robot, trained with GIB for bidding and ACBL human game hands for play.

The results were intriguing, demonstrating that the robots are formidable players, even against strong human competition. Click here for the full leaderboard.

In the subsequent Zenith Daylong Reward simulation, we introduced "Thinking Ben," another robot variation "trained" by Lorand Dali, to the robot lineup.

  1. In the world of bridge, if a partner is hiding information, that's not good. if the enemy is hiding information, TD can punish him. BBO, would you be so kind as to write down the name of the robot that is on the table. Also would you kind to give us a complete system and style gibs play by robots name. Thanks.

  2. Who bots were playing against when replaying these two tourneys? Against other bots? If yes, the whole experiment shows very little
