WebThe above algorithms are among the best general algorithms which operate on a graph without preprocessing. However, in practical travel-routing systems, even better time complexities can be attained by algorithms which can pre-process the graph to attain better performance. One such algorithm is contraction hierarchies. Dijkstra's algorithm WebThe algorithm walks up the graph from the furthest-away edges and places FDTs and FDHs as needed to support the downstream units of consumption 2.
