On More Efficiently and Versatilely Querying Historical k-Cores

Summary: 'Core time shell' and MCTS-index expose hierarchical core-time structure to avoid full-vertex scans, yielding approximately optimal historical k-core query time with PHC-like space. MCTS also enables a novel 'when' query and empirically outperforms PHC. (summarized by gpt-5-mini on Feb 09 2026)
