We propose a new unbiased estimator for estimating the utility of the optimal stopping problem. The MUSE, short for ‘Multilevel Unbiased Stopping Estimator’, constructs the unbiased Multilevel Monte Carlo (MLMC) estimator at every stage of the optimal stopping problem in a backward recursive way. In contrast to traditional sequential methods, the MUSE can be implemented in parallel. We prove the MUSE has finite variance, finite computational complexity, and achieves ɛ-accuracy with O (1/ɛ 2) computational cost under mild conditions. We demonstrate MUSE empirically in an option pricing problem involving a high-dimensional input and the use of many parallel processors.
