CORE: a Complex Event Recognition Engine

Summary: CORE introduces an automaton-based CER engine supporting time windows and partition-by correlations while compactly representing partial matches. It achieves constant per-event maintenance and output-linear enumeration, outperforming prior systems by up to five orders of magnitude. (summarized by gpt-5.6-luna on Jul 24 2026)
