Struct KkParams 

pub struct KkParams {
    pub maxiter: usize,
    pub epsilon: f64,
    pub kkconst: f64,
    pub seed: Option<Vec<[f64; 2]>>,
}

Parameters for the 2D Kamada-Kawai layout.

Fields

maxiter: usize

Maximum number of iterations. Default: 10 * vcount.

epsilon: f64

Stop when the maximum energy-gradient magnitude squared falls below this threshold. Zero means run for exactly maxiter iterations.

kkconst: f64

Spring constant K. Default: vcount as f64.

seed: Option<Vec<[f64; 2]>>

Optional initial positions (row per vertex: [x, y]). If None, a scaled circle layout is used.

Implementations

impl KkParams

pub fn default_for(n: usize) -> Self

Reasonable defaults for a graph with n vertices.

Examples

use rust_igraph::KkParams;

let params = KkParams::default_for(100);
assert_eq!(params.maxiter, 1000);
