HiRAD: A Flexible Large-Scale AGV Routing System
Yunjie Huang, Ruizhong Wu, Mengxuan Zhang +3
Automatic Guided Vehicles (AGVs) substantially boost warehouse throughput, but routing large-scale AGV fleets remains challenging. Classical Multi-Agent Pathfinding solvers suffer…
Query-aware Routing for Filtered Approximate Nearest Neighbors Search
Qianqian Xiong, Mengxuan Zhang
Filtered ANN search, which combines vector similarity with attribute predicates, is a core primitive in modern vector databases and retrieval-augmented generation. We benchmark all…
Three Pillars Towards Next-Generation Routing System
Lei Li, Mengxuan Zhang, Zizhuo Xu +2
The routing results are playing an increasingly important role in transportation efficiency, but they could generate traffic congestion unintentionally. This is because the traffic…
High Throughput Shortest Distance Query Processing on Large Dynamic Road Networks
Xinjie Zhou, Mengxuan Zhang, Lei Li +1
Shortest path (SP) computation is the building block for many location-based services, and achieving high throughput SP query processing with real-time response is crucial for thos…
