TL;DR of the paper, generated automatically.

Faster nearest-neighbor search built on Delaunay construction history.

Queries: grid-based starting points give a twofold speedup, still exact.
Construction: parallel build is 10x faster, query cost nearly the same.
Claim: the paper says it beats widely used libraries on query speed.
