Graph coreness
WebThe k-core of a graph is the maximal subgraph in which every vertex has at least degree k. The cores of a graph form layers: the (k+1)-core is always a subgraph of the k-core. This function calculates the coreness for each vertex. WebDec 4, 2024 · So far, I've created this script which creates a circle plot. My problem is that the color of node should change according k-core. It means that outside of circle should be lighter and the center should be darker!: # Load Library library (igraph) library (RColorBrewer) # Classic palette for red, with 5 colors coul01 = brewer.pal (5, "RdPu") # I ...

WebJul 31, 2024 · Coreness can be described as the property of the node to belong to the densely connected part of the graph (higher node cores) or its periphery (lower node cores). Nodes with higher cores are typically referred to as influential nodes since they are able to spread information faster across the network than nodes with lower core values.
