WebGraphDifference gives the graph obtained from the union of vertex sets of two graphs and the complement of the second graph ’ s edge set with respect to the first. GraphComplement gives the graph that has the same vertex set as a given graph, but with edges corresponding to absent edges in the original (and vice versa). WebThe second issue is often handled by separating the product into repeating edges and non-repeating edges. For example, in 4, the correlations issue is subverted by assuming the edges to be k $$ k $$-wise independent, which causes the expected value of the product to be 0 unless all edges are repeating.The case of closed walks with all edges repeating, …
