In each stage Player 1 hides one or two pebbles in his hand, and his opponent has to guess that number; Player 1 loses a point if Player 2 is correct, and otherwise he wins a point. As soon as Player 1 hides one pebble, the players cannot change their choices in any future stage.\r\nBlackwell and Ferguson (1968) give an ε-optimal strategy for Player 1 that hides, in each stage, one pebble with a probability that depends on the entire past history. Any strategy that depends just on the clock or on a finite memory is worthless. The long-standing natural open problem has been whether every strategy that depends just on the clock and a finite memory is worthless. We prove that there is such a strategy that is ε-optimal. In fact, we show that just two states of memory are sufficient.\r\n","lang":"eng"}],"conference":{"end_date":"2018-06-22","name":"EC: Conference on Economics and Computation","location":"Ithaca, NY, United States","start_date":"2018-06-18"},"publication_identifier":{"isbn":["9781450358293"]},"publisher":"ACM Press","page":"149-150","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","external_id":{"isi":["000492755100020"]},"publication_status":"published","oa":1,"isi":1,"title":"The Big Match with a clock and a bit of memory","day":"18","date_published":"2018-06-18T00:00:00Z","scopus_import":"1","status":"public","has_accepted_license":"1","doi":"10.1145/3219166.3219198","oa_version":"Submitted Version","author":[{"last_name":"Hansen","full_name":"Hansen, Kristoffer Arnsfelt","first_name":"Kristoffer Arnsfelt"},{"orcid":"0000-0003-4783-0389","id":"3B699956-F248-11E8-B48F-1D18A9856A87","first_name":"Rasmus","last_name":"Ibsen-Jensen","full_name":"Ibsen-Jensen, Rasmus"},{"first_name":"Abraham","last_name":"Neyman","full_name":"Neyman, Abraham"}],"file_date_updated":"2020-07-14T12:47:14Z","_id":"5967","quality_controlled":"1","department":[{"_id":"KrCh"}]}
