Tutorial-8 Understanding the Basics of Graph Matrix …

For a simple graph with vertex set U = {u1, …, un}, the adjacency matrix is a square n × n matrix A such that its element Aij is one when there is an edge from vertex ui to vertex uj, and zero when there is no edge. The diagonal elements of the matrix are all zero, since edges from a vertex to itself (loops) are not allowed in simple graphs. It is also sometimes useful in algebraic graph theory to replace the nonzero elements with algebraic variables. The same concept can be ext… WebOther than representing graphs visually with vertices and edges, one can also represent them in terms of matrices.
