Multinomial selection problem: a study of BEM and AVC algorithms. (English) Zbl 05763933
Summary: The two well-known and widely used multinomial selection procedures Bechhofor, Elmaghraby, and Morse (BEM) and all vector comparison (AVC) are critically compared in applications related to simulation optimization problems.
Two configurations of population probability distributions in which the best system has the greatest probability \(p_i\) of yielding the largest value of the performance measure and has or does not have the largest expected performance measure were studied.
The numbers achieved by our simulations clearly show that none of the studied procedures outperform the other in all situations. The user must take into consideration the complexity of the simulations and the performance measure probability distribution properties when deciding which procedure to employ.
An important discovery was that the AVC does not work in populations in which the best system has the greatest probability \(p_i\) of yielding the largest value of the performance measure but does not have the largest expected performance measure.
