Generalized martingale
WebA GENERALIZED MARTINGALE BETTING STRATEGY Thus, ak = (a=b)bk which from Equation (1) gives, for k 2, ak(!) = a1f! k 1=1g +m a b bk 1(!)1f! k 1= 1g: (3) 3. The Average Amounts Bet Because !k 1 is independent of bk 1 and the average of an independent product is the product of the averages, the average amount bet on the kth Originally, martingale referred to a class of betting strategies that was popular in 18th-century France. The simplest of these strategies was designed for a game in which the gambler wins their stake if a coin comes up heads and loses it if the coin comes up tails.
