EdgeAdd[g, e]
makes a graph by adding the edge e to the graph g.

EdgeAdd[g, {e1, e2, ...}]
adds a collection of edges to g.


  • EdgeAdd[g, e] will add the edge e and create a multiple edge if the edge already exists in g.
  • An undirected edge can be specified using or UndirectedEdge[v, w].
  • A directed edge can be specified using or DirectedEdge[v, w].
