Heuristic Search as Language-Guided Program Optimization
Mingxin Yu, Ruixiao Yang, Chuchu Fan
Large Language Models (LLMs) have advanced Automated Heuristic Design (AHD) in combinatorial optimization (CO) in the past few years. However, existing discovery pipelines often re…
Joint Scheduling of DER under Demand Charges: Structure and Approximation
Ruixiao Yang, Gulai Shen, Ahmed S. Alahmed +1
We study the joint scheduling of behind-the-meter distributed energy resources (DERs), including flexible loads, renewable generation, and battery energy storage systems, under net…
Co-Optimizing Distributed Energy Resources under Demand Charges and Bi-Directional Power Flow
Ruixiao Yang, Gulai Shen, Ahmed S. Alahmed +1
We address the co-optimization of behind-the-meter (BTM) distributed energy resources (DER), including flexible demands, renewable distributed generation (DG), and battery energy s…
Optimization of Multi-Agent Flying Sidekick Traveling Salesman Problem over Road Networks
Ruixiao Yang, Chuchu Fan
The mixed truck-drone delivery systems have attracted increasing attention for last-mile logistics, but real-world complexities demand a shift from single-agent, fully connected gr…
