gives the reciprocity of a graph g.
uses rules vw to specify the graph g.
- The reciprocity of a graph g is the fraction of reciprocal edges over all edges of g.
- For a directed graph, the edges and are reciprocal and form a cycle of length 2.
- For an undirected graph, all edges are reciprocal.
- GraphReciprocity works with undirected graphs, directed graphs, and weighted graphs.
