Struct CommunityDetection 

Source 
pub struct CommunityDetection;
Expand description

Community detection via modularity maximization.

Modularity Q = (1/2m) Σ_{ij} [A_{ij} - k_i k_j / 2m] δ(c_i, c_j)

Implementations§

Source§

impl CommunityDetection

Source

pub fn modularity(graph: &NetworkGraph, communities: &[usize]) -> f64

Computes modularity Q for a partition given by communities (node → community id).

Source

pub fn greedy_modularity(graph: &NetworkGraph) -> Vec<usize>

Greedy modularity maximization (Clauset-Newman-Moore simplified).

Starts with each node in its own community and greedily merges. Returns the best community assignment found.

Source

pub fn n_communities(communities: &[usize]) -> usize

Returns number of communities in a partition.
