VP Tree Search
VP Tree Search VP tree search (vantage point tree) organizes points in a metric space by selecting a pivot point and partitioning others based on distance from that pivot. It is designed for efficient nearest neighbor search using triangle inequality based pruning. Problem Given a set of points $S$ in a metric space and a query point $q$, find: $$ \arg\min_{p \in S} d(p, q) $$ Structure Each node stores:...
