The Maximum Trajectory Coverage Query in Spatial Databases

Summary: Introduces kBFT and kBCovFT, including the latter’s non-submodular NP-hard coverage objective. The TQ-tree combines quadtree hierarchy with intra-node Z-ordering for trajectory-locality pruning, yielding 2–3 orders-of-magnitude speedups. (summarized by gpt-5.6-luna on Jul 24 2026)
