Move By Nature

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:

    “Glorious bouquets and storms of applause ... are the trimmings which every artist naturally enjoys. But to move an audience in such a role, to hear in the applause that unmistakable note which breaks through good theatre manners and comes from the heart, is to feel that you have won through to life itself. Such pleasure does not vanish with the fall of the curtain, but becomes part of one’s own life.”
    —Dame Alice Markova (b. 1910)

    “The moral virtues, then, are produced in us neither by nature nor against nature. Nature, indeed, prepares in us the ground for their reception, but their complete formation is the product of habit.”
    —Aristotle (384–322 B.C.)
