Subgraph with same number of edges as original graph

I currently have an efficient algorithm for generating the subgraphs of a graph (using the boost library). My question, the answer to which though seemingly obvious, is more on the theoretical side: c[详细]

Javascript directed acyclic graph library? (Graph visualization is NOT necessary)

I have a dataset which is best represented by a graph.It consists of nodes of 6 or 7 different \"types\" with directed edges (dependencies on one another, guaranteed not to have cyclic dependencies).T[详细]

Difference between Hamiltonian path and ST

I was reading up algorithms for finding the minimum spanning tree(in case of weighted graphs) and for finding if a graph has a hamiltonian path(which depends on the presence of a hamiltonian cycle). I[详细]

Any working example of VF2 algorithm?

I have been reading the VF2 algorithm for finding if two graphs are isomorphic but am somehow missing the big picture. Could be that I am missing the relevant background in this area but all I see is[详细]
