Battery-Swapping Station Operation Under Forecast Uncertainty: A Scenario-Based Stochastic MPC Framework
Zhiyuan Guo, Siyang Gao, Zhichao Chen +2
Battery-swapping stations (BSSs) can shorten electric-vehicle energy replenishment while using centrally managed battery inventories as flexible grid-connected storage. Realizing b…
A Min-Max Gradient Search Method for Constrained Simulation Optimization
Ruiyang Jin, Siyang Gao, Henry Lam
Constrained simulation optimization (CSO) is a general framework for optimizing stochastic systems under performance constraints. It arises widely in practice where objective and c…
On the Reliability Limits of LLM-Based Multi-Agent Planning
Ruicheng Ao, Siyang Gao, David Simchi-Levi
This technical note studies the reliability limits of LLM-based multi-agent planning as a delegated decision problem. We model the LLM-based multi-agent architecture as a finite ac…
Query-Efficient Zeroth-Order Algorithms for Nonconvex Constrained Optimization
Ruiyang Jin, Yuke Zhou, Yujie Tang +2
Zeroth-order optimization (ZO) has been a powerful framework for solving black-box problems, which estimates gradients using zeroth-order data to update variables iteratively. The…
A Zeroth-Order Extra-Gradient Method for Black-Box Constrained Optimization
Yuke Zhou, Ruiyang Jin, Siyang Gao +2
Non-analytical objectives and constraints often arise in control systems, particularly in problems with complex dynamics, which are challenging yet lack efficient solution methods.…
