Kinds of chain reaction "effects": BUTTERFLY, DOMINO, RIPPLE, SNOWBALL
This map illustrates the OsmAnd routing concept. The route starts in the Start Area Cluster (221558), moves to the nearest Border Point, and continues through precomputed Shortcuts across intermediate clusters. It then enters the Finish Area Cluster (221536) via another border point and finishes using local roads. This method speeds up routing by combining local search with efficient inter-cluster shortcuts.
