The

Adjacency matrix [A.sup.(k)] of the workflow graph is drawn.

Then each thread examines the cycle existence of combination row vertices to see if they form a cycle or not regardless of the vertices order in the set by using a technique called "virtual

adjacency matrix" test.

A = ([a.sub.ij]) [member of] [R.sup.nxn] is called the weighted

adjacency matrix of G with nonnegative elements and [a.sub.ij] > 0 if and only if j [member of] [N.sub.i].

They exploit the duality between the canonical representation of graphs as abstract collections of vertices with edges and a sparse

adjacency matrix representation.

In this paper, we consider the

adjacency matrix for RC-graphs and the eigen values are taken into account and a handful of results are obtained.

The matrix based on the prey-predator link, a binary relation, is, in fact, the

adjacency matrix (defined below) of the digraph associated with a food web.

We read the graph in the form of an

adjacency matrix adjMatrix [][].

The node-node

adjacency matrix A of the graph [G.sub.A] is an [n.sub.A] x [n.sub.A] matrix which is then given by

This book examines how data mining can be implemented to identify consumer patterns through such approaches as chance discovery, knowledge discovery, discourse analysis and the

adjacency matrix. With its focus on using social data for marketing and design research, this volume is written for students and researchers headed for a career that includes website design, database retrieval, e-commerce and global teamwork projects.

The methods proposed so far are based on

adjacency matrix [1], distance matrix [2] to determine the structurally distinct mechanisms of a kinematic chain; the link disposition method [3], the flow matrix method [4], and the row sum of extended distance matrix methods [5] are used.
