WebJan 10, 2013 · For heap implementation, you could use an array. For indexing, use a Hash Map, with Vertex number as the key and its index in heap as the value. When we want to update a vertex, search its index in the Hash Map in O (1) time. Reduce the vertex distance in heap and then keep traversing up (Check its new distance against its root, if root's … WebApr 10, 2024 · Algorithms for Routing and Solving the Traffic Assignment Problem. c-plus-plus algorithm r rcpp distance parallel-computing isochrones shortest-paths dijkstra-algorithm frank-wolfe bidirectional-a-star-algorithm traffic-assignment contraction-hierarchies algorithm-b.

WebApr 6, 2024 · Dijkstra algorithm is a generalization of BFS algorithm to find the shortest paths between nodes in a graph. For a given graph G = (V, E) and a distinguished vertex s, then we can find the shortest path from s to every other vertex in G with the help of Dijkstra algorithm. This algorithm uses the greedy method as it always picks the next ...
