Diversifying Top-K Results

Summary: Introduces a general score-free diversified top-k framework that retrofits existing top-k engines via sufficient/necessary stopping conditions and div-search-current(). A*-, DP-, and cut-based algorithms culminate in div-cut, which optimally handles k up to 2,000 in seconds. (summarized by gpt-5.6-luna on Jul 24 2026)
