For well-distributed points, nearest neighbor search is often near O(logn)O(\log n)O(logn) in practice. In the worst case (all points clustered tightly or along a line), it can degrade to O(n)O(n)O(n), but this is uncommon with typical spatial data.

OsmAnd has always been about putting you in control. Our original A* routing engine, configurable via routing.xml, offered immense power. You could define intricate profiles, avoid specific road types, and truly personalize your journey. With maps optimized for minimal storage (the entire planet's car data for our new HH-routing is around a mere 800MB!), OsmAnd was a lean, mean navigating machine.
