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:
“Life seems to be an experience in ascending and descending. You think you’re beginning to live for a single aim—for self-development, or the discovery of cosmic truths—when all you’re really doing is to move from place to place as if devoted primarily to real estate.”
—Margaret Anderson (1886–1973)
“The savior who wants to turn men into angels is as much a hater of human nature as the totalitarian despot who wants to turn them into puppets.”
—Eric Hoffer (1902–1983)
