⛰ alps

alps makes it easy to solve linear programming problems.

it can also be used a library

use alps::{solve, UnoptimizedProblem};

fn main() {
    // Load the problem from a file
    let file_str = std::fs::read_to_string("problems/bakery.json").expect("Failed to read the file");

    // Deserialize the problem
    let problem: UnoptimizedProblem = serde_json::from_str(&file_str).expect("Failed to deserialize the problem");

    // Solve the problem
    let solution = solve(&problem);

    // Print the solution
    println!("{:?}", solution);
}
