Creates a copy of the graph. Attributes are copied by reference; in other words, if you use mutable Python objects as attribute values, these objects will still be shared between the old and new graph. You can use `deepcopy ()` from the `copy` module if you need a truly deep copy of the graph. WebMay 7, 2024 · Graphlet Degree Vector A graphlet is a collection of nodes, that can contribute to a subgraph of a given network. This counts the number of graphlets rooted at each given node (up to a given size or of a given type). The graphlet degree vector is a vertical column of how many graphlets of a particular count appears rooted at a given node. spencer toby
