We identify the nature of sampling plans that characterize efficient algorithms, particularly in large countable spaces. We show that in a certain asymptotic sense, the optimal sampling characterization, that is, the sampling budget for each system that guarantees optimal convergence rates, depends on a single easily estimable quantity called the score. This result provides a useful and easily implementable sampling allocation that approximates the optimal allocation, which is otherwise intractable due to it being the solution to a difficult bilevel optimization problem. Our results point to a simple sequential algorithm for efficiently solving large-scale constrained simulation optimization problems on finite sets. © 2012 IEEE.||Source Title:||Proceedings - Winter Simulation Conference||URI:||http://scholarbank.nus.edu.sg/handle/10635/72303||ISBN:||9781467347792||ISSN:||08917736||DOI:||10.1109/WSC.2012.6465141|
