Struct BetweennessCentrality 

Source 
pub struct BetweennessCentrality;
Expand description

Betweenness Centrality algorithm implementation.

Betweenness centrality quantifies the number of times a node acts as a bridge along the shortest path between two other nodes.

Implementations§

Source§

impl BetweennessCentrality

Source

pub fn compute<T: Transaction>( tx: &T, config: &BetweennessCentralityConfig, ) -> GraphResult<CentralityResult>

Compute betweenness centrality for all nodes in the graph.

Uses Brandes’ algorithm for efficient O(V*E) computation.

§Arguments
  • tx - The transaction to use for graph access
  • config - Configuration parameters for the algorithm
§Returns

A CentralityResult containing scores for all nodes.

Source

pub fn compute_for_nodes<T: Transaction>( tx: &T, nodes: &[EntityId], config: &BetweennessCentralityConfig, ) -> GraphResult<CentralityResult>

Compute betweenness centrality for a subset of nodes.

Only considers shortest paths within the specified subgraph.

§Arguments
  • tx - The transaction to use for graph access
  • nodes - The nodes to include in the computation
  • config - Configuration parameters for the algorithm
