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.
5The same properties also contributed to Nazi Germany’s strategy against agar’s scarcity, which — besides being supplied from Japan by submarine — relied on large pre-war stocks and on recovery methods to reuse bacteriological agar by autoclaving (boiling at around 121°C, 250°F, in a pressurized container for 30 to 60 minutes), thus liquefying and sterilizing the jelly, before purifying it again.
