bellmanFordAlgorithm
Computes shortest paths from a single source in a directed graph.
Include Headers
seqan/graph_algorithms.h
Parameters
In-parameter:A directed graph. Types: Directed Graph | |
In-parameter:A source vertex. Types: VertexDescriptor | |
In-parameter:A weight map. Remarks: A property map with edge weights. Edge weights may be negative. | |
Out-parameter:A property map. Remarks: A property map that represents predecessor relationships among vertices. It determines a shortest-paths tree. | |
Out-parameter:A property map. Remarks: Indicates for each vertex the distance from the source. |
Remarks
Edge weights may be negative in the Bellman-Ford algorithm.
The out parameters are only valid if the algorithm returns true.
Return Values
True if the graph has no negative weight cycles, false otherwise.
