Fast Network K-function-based Spatial Analysis

Summary: Proposes count augmentation (CA) and neighbor sharing (NS) to accelerate network K-function computation on spatial networks. Integrates shortest path sharing (ASPS) to reduce worst-case complexity, delivering up to 165.85x speedups over prior methods. (summarized by gpt-5-nano on Feb 09 2026)
