On the centrality in a graph
WebI know this is a pretty old question, but just wanted to point out that the reason why your degree centrality values are all 1 is probably because your graph is complete (i.e., all … Web8 de jan. de 2024 · IMO, you should consider a different centrality algorithm for a graph of this size. In the end, the results don't differ too much between algorithms and usually, the bigger your graph is, the less you care about accurate centrality values for each and every vertex. The classic PageRank algorithm, for example, runs perfectly fine on larger graphs.
