| | Determinacy - Wikipedia, the free encyclopedia |
 | | In set theory, a branch of mathematics, determinacy is the study of under what circumstances one or the other player of a game must have a winning strategy, and the consequences of the existence of such strategies. |
 | | Informally, a strategy for a player is a way of playing in which his plays are entirely determined by the foregoing plays. |
 | | More formally, a strategy for player I (for a game in the sense of the preceding subsection) is a function that accepts as an argument any finite sequence of natural numbers, of even length, and returns a natural number. |
