Sentence examples for graphs are undirected from inspiring English sources

We shall denote the weight of the edge joining nodes υ and w by μ υ, w); notice that μ υ, w) = μ w, υ) because the graph is undirected.

The graph G = (V, E, W) is then mapped to an adjacency matrix representation that consists of a | V| × | V| = n × n matrix A: (3) A = a 11 ⋯ a 1 n ⋮ ⋱ ⋮ a n 1 ⋯ a n n,   n = V,     a i, j    ∈ 0,1000 ⊂ N. Because the graph is undirected the adjacency matrix is symmetric and therefore a ij = a ji.
