In this framework, one is aiming at distributing the balls in a set of bins according to certain rules, and in order to This balls-and-bins game closely models memory-access. Each ball is thrown into a uniformly random bin, independent of other balls, which implies that the probability that a ball falls into any given bin is 1/n. by Crane Fluid Systems.

Then the maximum load, or the most balls in any bin, is approx-imately with high probability. Suppose in-stead that the balls are placed sequentially, and each ball is placed in the least loaded of bins chosen inde-pendently and uniformly at In the standard balls-and-bins model of balanced allocations, m balls are placed sequentially into n bins. 3150/18-BEJ1097￿. S. Balls-and-bins games have been a wildly successful tool for modeling load balancing problems. Sanders et al. In [7], the author shows that the expected maximum load is smaller if we allocate n/2 chains of length 2 with one random choice per chain, compared to n balls into n bins with d = 2. Classically, such problems are modeled as static balls into bins processes, where m balls (tasks) are to be distributed among n bins (servers).
