I have been using `r_c_shortest_paths` for a while, and recently because of a code refactoring I realised that one of the template parameters, namely `EdgeIndexMap`, seems not to be used...
The ResourceExtensionFunction in r_c_shortest_paths takes a new and an old resource container. To me, in the docs it is unclear whether * the new Resource_Container is a copy of the...
This fixes a bug when num_vertices() returns a value that does not match the actual number of vertices. This happens for instances of filtered_graph. The fix involves looping over the...
In the documentation the `DFSVisitor` is taken by reference: https://www.boost.org/doc/libs/1_80_0/libs/graph/doc/depth_first_visit.html , while in the actual header it is taken by copy. I assume the code in the header is by...
The Held-Karp lower bound for the TSP is a good lower bound for the TSP and at a big picture, it attempts to approximate the TSP from below by trying...
Dear all, Recently, I was working on a Flow Decomposition Problem, and found out that there are not many datasets for large valid flow networks. Nor could I find any...
When calculating spptw, these four parameters all should be 'opt_sloutions_spptw'.
Suppose we have two triangles, one have vertexes 0, 1, 2, the other have vertexes 3, 4, 5, then we use planar_face_traversal to traversal it, we will get 4 faces:...
Here is my code. My code is trying to find common subgraph between graph1 and graph2 with specific number of vertices. ``` #include #include #include #include #include #include #include #include...
Hi, GraphViz provides a native C API, called cgraph. This adds supports for cgraph in a similar way to existing leda_graph.hpp and stanford_graph.hpp implementations. The implementation already works well and...
