Binary adjacency matrix
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. If the graph is undirected (i.e. all of its edges are bidirectional), the adjacency matrix is sy…

WebThe adjacency matrix of G = ( V,E) is the n ⨯ n matrix A indexed by V, whose ( u, v )-entry is defined as. Recall that a matrix is said to be reducible if it can be transformed to the form. where A ′ and A ′′ are square matrices, by simultaneous row/column permutations. Otherwise, A is said to be irreducible. WebLet N be the set of n elements {1, 2, … , n} and E a binary relation: E ⊆ N × N, also denoted by an arrow, →. Consider N to be the set of nodes of a directed graph G, and E the set of arcs (directed edges). A directed graph G may be represented by its adjacency matrix A (Fig. 11.1), an n × n boolean matrix whose
