In GraphX, a vertex is represented as a unique 64-bit-long identifier, vertexID. There are no constraints on ordering of these identifiers. Edges of the graph also have corresponding source and vertex identifiers. The Graph class has members to access the vertices and edges of the graph....

Distance-patterns of vertices in a graph Given a connected simple (p,q)-graph G=(V,E) and ≠MV, we initiate a study of the set-valued function f:V→2 M -{}, called the M-distance-pattern of G, which associates with each vertex u∈V the set f M (u)={d(u,v):v∈M}, ca...
