The dashed circle shows the current best distance. As the algorithm finds closer points, the circle shrinks, which causes more subtrees to fail the "could contain a closer point?" test and get pruned. The search usually gets cheaper as it progresses.
Leveraging the findings found, optimize the crate such that ALL benchmarks run 60% or quicker (1.4x faster). Use any techniques to do so, and repeat until benchmark performance converges, but don’t game the benchmarks by overfitting on the benchmark inputs alone 1
