In game theory a move by nature is a decision or move in an extensive form game made by a player who has no strategic interests in the outcome. The effect is to add a player, 'Nature' whose practical role is to act as a random number generator. For instance, a game of Poker requires a dealer to choose which cards a player is dealt, the dealer plays the role of the Nature player

Famous quotes containing the words move and/or nature:
“When Shakespeare copied chroniclers verbatim, it was because he knew they were good enough for his audiences. In a more polished age he who could so move our passions, could surely have performed the easier task of satisfying our taste.”
—Horace Walpole (1717–1797)
“That life is really so tragic would least of all explain the origin of an art form—assuming that art is not merely imitation of the reality of nature but rather a metaphysical supplement of the reality of nature, placed beside it for its overcoming.”
—Friedrich Nietzsche (1844–1900)
