Description

Runs Leiden community detection optimizing (weighted) modularity. - For undirected graphs, uses the standard modularity objective. - For directed graphs, uses the directed modularity formulation. - resolution corresponds to the modularity resolution parameter (gamma). - When edgeWeightAttribute is NULL/empty, every edge has weight 1. Writes the resulting community id into a node attribute (created when missing) of type CXUnsignedIntegerAttributeType and dimension 1. Returns the number of detected communities, or 0 on failure.

Signature

CX_EXTERN CXSize CXNetworkLeidenModularity( CXNetworkRef network, const CXString edgeWeightAttribute, double resolution, uint32_t seed, CXSize maxLevels, CXSize maxPasses, const CXString outNodeCommunityAttribute, double *outModularity );
