Description
**Status as of Sep 10, 2026:**
Determinant diversity algo is already present in main branch. The algorithm is integrated with bechmarks. But the algorithm is inefficient. Kiran is working on better implementation of the algorithm. Once it is ready, it needs to be integrated into the code. This PR has a slightly better algorithm implementation and needs to be replaced with final version from KIran.
https://github.com/microsoft/DiskANN/pull/1249 draft PR covers this partially completed work.

Research direction
Start by reviewing the existing determinant diversity algorithm in the main branch and the partially completed draft PR #1249. Compare that implementation with Kiran's planned final version, then integrate the replacement and verify the existing benchmarks cover recall and performance improvements.
