This function implements the directed random walk algorithm proposed by Liu et al (2013). It evaluates the topological weight of each gene according to its topological importance in the global pathway graph. The genes that close to many other genes that have large initial weights will receive larger weights. The final weights reflect the topological importances of genes in the global pathway graph.
