Abstract:

BA scale free network model describes the evolutionary character of most networks in nature and human society. However, we lack software to simulate the evolution of BA network to illustrate its properties of growth and preferential attachment. In view of the lack, we developed a software package via Labview combined with Matlab. We apply Labview to construct the humanmachine interface and to realize the evolution animation. Matlab is utilized to compute all the data such as adjacent matrix, node degrees and attachment probabilities. The evolution of the network can be vividly shown by adding node after node when a command button is clicked again and again. The software is beneficial to learn and understand the BA model of scale free networks. An example the BA scalefree evolution is given, and the results show that the software is capable not only of displaying the process of the network evolution, but also of dynamic calculation of the adjacent matrix, node degrees and attachment probabilities.
