Enumeration of spanning trees of graph: alternative methods
All the trees of the graph are not important, but spanning trees have a special significance in the analysis of networks and systems. The simplest of the prototype methods is based on incidence matrix. Two new approaches have been proposed in this paper, which makes use of few other matrices used to represent topology of the network graph. Some optimisation techniques are also developed to reduce the number of calculations and computer time as well. Comparison is made between prototype and proposed methods using programs developed in MATLAB. Efficiency of the proposed method is proved with a simple case study.
