Figure 2From: Hierarchical decomposition of dynamically evolving regulatory networksIllustration of the key difference between D-HIDEN and the classical hierarchical decomposition algorithms, such as HIDEN. The HIDEN method in the figure can be replaced by any existing hierarchical decomposition method without losing generality. HIDEN computes the hierarchy of all the networks G i independently. On the other hand, D-HIDEN updates the hierarchy of each network G i based on the topological difference between G i and G i−1, and the existing hierarchy H i−1 of G i−1.Back to article page
