WebEin Graph ist in der Graphentheorie eine abstrakte Struktur, die eine Menge von Objekten zusammen mit den zwischen diesen Objekten bestehenden Verbindungen repräsentiert. Die mathematischen Abstraktionen der Objekte werden dabei Knoten (auch Ecken) des Graphen genannt. Die paarweisen Verbindungen zwischen Knoten heißen Kanten (manchmal auch ... WebThe Louvain algorithm is a hierarchical clustering algorithm, that recursively merges communities into a single node and executes the modularity clustering on the condensed graphs.
