WebThe intersection graph of a family S is a graph G with V ( G) = S such that two elements s 1, s 2 ∈ S are adjacent in G if and only if s 1 ∩ s 2 ≠ ∅. The elements of S must be finite, hashable, and the elements of any s ∈ S must be hashable too. sage: graphs.IntersectionGraph( [ (1,2,3), (3,4,5), (5,6,7)]) Intersection Graph: Graph on ... WebThe matrix of distances. This matrix has size n 2 and associates to any u v the distance from u to v. The vector of eccentricities. This vector of size n encodes for each vertex v the distance to vertex which is furthest from v in the graph. In particular, the diameter of the graph is the maximum of these values.
