pub fn hyperbolicity(graph: &Graph) -> Result<f64, IgraphError>Expand description
Compute δ-hyperbolicity as a floating-point value.
Convenience wrapper around hyperbolicity_twice that returns δ
as f64.
§Examples
use rust_igraph::{Graph, hyperbolicity};
let g = Graph::from_edges(&[(0,1),(1,2),(2,3),(3,0)], false, Some(4)).unwrap();
assert!((hyperbolicity(&g).unwrap() - 1.0).abs() < 1e-10);
