Function hercules::local_search::simple_local_search

pub fn simple_local_search(
    qubo: &Qubo,
    x_0: &Array1<usize>,
    max_steps: usize
) -> Array1<usize>

Given a QUBO and an integral initial point, run simple local search until the point converges or the step limit is hit.

Example:

use hercules::qubo::Qubo;
use smolprng::{PRNG, JsfLarge};
use hercules::{initial_points, utils};
use hercules::local_search;

// generate a random QUBO
let mut prng = PRNG {
  generator: JsfLarge::default(),
};
let p = Qubo::make_random_qubo(10, &mut prng, 0.5);

// generate a random point inside with x in {0, 1}^10 with
let x_0 = initial_points::generate_random_binary_point(&p, &mut prng, 0.5);

// perform a simple local search starting at x_0
let x_sol = local_search::simple_local_search(&p, &x_0, 1000);
