Fig. 10From: Topology dependence of on-demand ride-sharingIllustration of the coarse graining process. a The original network. b The three nodes in the center are smaller than a predefined buffer. c Hence they are merged into a single node. d In each of the edges, intermediary nodes are introduced so that most of the new edges have the same edge length. Note that at one end of the original edges, the new edge is slightly smaller than the target lengthBack to article page
