Struct DhParams 

pub struct DhParams {
    pub maxiter: u32,
    pub fineiter: u32,
    pub cool_fact: f64,
    pub weight_node_dist: f64,
    pub weight_border: f64,

}

Parameters for the Davidson-Harel layout.

Fields

maxiter: u32

Maximum annealing iterations. Default: 10.

fineiter: u32

Fine-tuning iterations. Default: max(10, log2(n)).

cool_fact: f64

Cooling factor in (0, 1). Default: 0.75.

weight_node_dist: f64

Weight for node-node distance repulsion. Default: 1.0.

weight_border: f64

Weight for border proximity. Default: 0.0.

weight_edge_lengths: f64

Weight for edge length minimization. Default: density/10.

weight_edge_crossings: f64

Weight for edge crossing minimization. Default: 1 - sqrt(density).

weight_node_edge_dist: f64

Weight for node-edge distance (fine-tuning only). Default: (1-density)/5.

Implementations

impl DhParams

pub fn for_graph(graph: &Graph) -> Self

Create parameters with defaults scaled to the given graph.

Examples

use rust_igraph::{Graph, DhParams};

let g = Graph::with_vertices(10);
let params = DhParams::for_graph(&g);
assert_eq!(params.maxiter, 10);
assert!(params.cool_fact > 0.0 && params.cool_fact < 1.0);
