    Sample Complexity and Solution Schemes for Data-driven Multistage Stochastic Programming under Markov Dependent Uncertainty

    Department of Industrial Engineering and Management Sciences (IEMS)

    11:00 AM A230, Technological Institute

    EVENT DETAILS

    Abstract:

    This work addresses the computational limitations of the Sample Average Approximation (SAA) method in multistage stochastic programming under Markov-dependent data processes. While SAA is effective for static and two-stage stochastic optimization problems, it becomes computationally prohibitive in multistage settings as the number of samples required to obtain a reasonably accurate solution grows exponentially in the time horizon $T$—a phenomenon known as the curse of dimensionality. To overcome this challenge, we propose a novel data-driven approach: the Markov Recombining Scenario Tree (MRST) method, combined with Stochastic Dual Dynamic Programming (SDDP) as a solution framework. Our analysis shows that MRST achieves polynomial sample complexity in $T$, offering an efficient data-driven alternative to SAA. Extensive numerical experiments further validate the effectiveness of MRST, showcasing its potential to mitigate the curse of dimensionality in multistage stochastic programming.
