Querying Cohesive Subgraphs in Temporal Graphs
Summary: Introduces a unified index for historical cohesive-subgraph queries over non-overlapping, monotonic CSMs, rather than model-specific structures. Reduces His-CC and His-Core to a canonical spanning-connected-component query, yielding up to 60×/100× speedups. (summarized by gpt-5.6-luna on Jul 26 2026)
