Efficient Locally h-Clique Densest Subgraph Discovery via Divide-and-Conquer

Summary: Introduces a divide-and-conquer algorithm for locally h-clique densest subgraph discovery, avoiding redundant computation while enumerating multiple locally optimal dense regions. Experiments on 15 large graphs show up to 100× speedups over the state of the art. (summarized by gpt-5.6-luna on Aug 28 2026)
