Nettet3. apr. 2024 · C++ Algorithm library Sorts the elements in the range [ first , last) in non-descending order. The order of equal elements is not guaranteed to be preserved. NettetJohnson Algorithm is used to find shortest paths between every pair of vertices in a given weighted directed graph and here weights may be negative. Johnson Algorithm uses both Dijkstra and Bellman-Ford algorithms as subroutines. Floyd-Warshall is most effective for dense graphs, while Johnson algorithm is most effective for sparse graphs.
