The evolution of stable elements identified by 100 runs of Combo presented as a Sankey diagram. Each stable element is presented using a box. The right most column represents the stable elements identified for Elite500. We increase the size of the network by adding 20% more nodes, therefor the next column represent Elite600. In each column there is a box labeled L*_O, which represents the nodes that will eventually join the network as the number of followers restriction relaxes. Theres is also another box labeled L*_U per column which represents the unstable elements (Single nodes).
