Abstract: Simulation optimization is a widely used tool in the analysis and optimization of complex stochastic systems. The majority of the previous works on simulation optimization rely heavily on detailed system information, such as the distributions of input variables and the system dynamics. However, it is usually costly and even unrealistic to obtain such detailed information in practice. To overcome this difficulty, new methods are needed to solve stochastic optimization problems based on simulation outputs or real-world data and fairly limited knowledge of the underlying system, i.e., in a blackbox setting. In this paper, we provide an up-to-date overview of the subject of blackbox simulation optimization, which has only been attracting attention from the simulation community in recent years. We discuss some of the new stochastic approximation algorithms developed recently for blackbox stochastic optimization. We also discuss challenges and potential future research opportunities.
