The analyses used an expanded link-link relationship matrix and an expanded pair-link occurance matrix to store information used to identify the next search direction, which improves th.

A novel approach,Extended Adjacency Matrix representation,to internally represent graph structure is proposed which combines adjacency matrix with adjacency list and orthogonal list allowing for the fastest possible access to different types of information on a directed graph.

Based on the coordination relationship between primary protection and backup protection and utilizing node adjacency matrix of directed graph of coordination dependency relationship,a novel method to determine optimal coordination sequence of directional protections in mesh network is proposed.

This paper presents a minimal cut set method based on the adjacent terminal matrix,which can be used to evaluate the reliability of main electric connection schemes for the railway station-oriented.

In the analytical ventilation network,“the passage method” and “the complementary divisor method of the branch matrix of the adjoining node” are adopted for the first time, and the effect of the system is proved very good.
