On the average of the number of the Maximal (and Minimal) Number of Balls upon throwing, 1, balls into , 2, bins T times By Shalosh B. Ekhad Suppose you throw, uniformly at random,, 1, balls into , 2, boxes , T times Let , A(T), be the average of the Maximum number of balls minus , T/2 Then A(T) satisfies the following linear recurrence equation with polynomial\ coefficients A(T - 1) A(T) = -------- + A(T - 2) T - 1 Subject to the initial conditions A(1) = 1/2, A(2) = 1/2 and in Maple notation A(T) = 1/(T-1)*A(T-1)+A(T-2) Using this recurrence we can compute many terms. 1/2 This enables us to estimate that A(T) is asympotically, C T where C is approximately, 0.3989 Suppose you throw, uniformly at random,, 1, balls into , 2, boxes , T times Let , A(T), be the average of the Minimum number of balls minus , T/2 Then A(T) satisfies the following linear recurrence equation with polynomial\ coefficients A(T - 1) A(T) = -------- + A(T - 2) T - 1 Subject to the initial conditions A(1) = -1/2, A(2) = -1/2 and in Maple notation A(T) = 1/(T-1)*A(T-1)+A(T-2) Using this recurrence we can compute many terms. 1/2 This enables us to estimate that A(T) is asympotically, C T where C is approximately, -0.3989 -------------------------- This took, 1.238, seconds.
