Adaptive simulation using perfect control variates [pdf]Paper  abstract   bibtex   
We introduce adaptive-simulation schemes for estimating performance measures for stochastic systems based on the method of control variates. We consider several possible methods for adaptively tuning the control-variate estimators, and describe their asymptotic properties. Under certain assumptions, including the existence of a ``perfect control variate'', all of the estimators considered converge faster than the canonical rate of $n^{−1/2}$, where $n$ is the simulation runlength. Perfect control variates for a variety of stochastic processes can be constructed from ``approximating martingales.'' We prove a central limit theorem for an adaptive estimator that converges at rate $n^{−1}\sqrt{łn n}$. A similar estimator converges at rate $n^{−1}$. An exponential rate of convergence is also possible under suitable conditions.
