To improve the asymptotic results via traditional methods, we introduce an algorithm which is similar to Newton-Raphson method. Assuming that the restricted growth functions of order 2 are uniformly distributed, we obtain the asymptotic formulae for the expectation and variance of the maximum in a random restricted growth function of order 2. Finally, we verify that the distribution of maximum in restricted growth functions of order 2 will converge to a normal distribution.近似常態性Hayman admissible 函數機率分佈限制成⾧函數鞍點法asymptotic normalityHayman admissible functionsprobability distributionrestricted growth functionssaddle-point method
