The rank of D ( G), denoted r a n k d ( G), is called the distance rank of G. Open source routing engine for OpenStreetMap customized to support Distance Matrix feature - graphhopper-matrix/IsochroneExample. Redundant computations can skipped (since distance is symmetric, distance (a,b) is the same as distance (b,a) and there's no need to compute the distance twice). It can handle vehicle routing problems complicated by your business-specific side constraints. Return multiple routes using Graphhopper. To do the road snapping I am using. Since points 2 and 4 are the closest to each other, these 2 points are put together to form a single group. Update: performance improvement can be achieved via landmarks. It would be nice to use Graphhopper to calulate a distance matrix (or Origin / Destination) matrix from a list of nodes. The larger distance_influence is the more GraphHopper will prioritize routes with a small total distance. To optimize it, we would need to re-arrange the stops order, and for this, we first need to get or calculate a 4x4 distance matrix.
