Function forest_graph 

pub fn forest_graph<R: Rng>(
    _tree_sizes: &[usize],
    sizes: &[usize],
    rng: &mut R,
) -> Result<Graph<usize, f64>>

Generates a random forest (collection of trees)

Creates a forest by generating multiple random trees and combining them into a single graph. The trees are disjoint (no edges between different trees).

Arguments

• tree_sizes - Vector specifying the size of each tree in the forest
• rng - Random number generator

Returns

• Result<Graph<usize, f64>> - A forest containing the specified trees
