Expand description

Trait for optimization solvers.

Any struct implementing this trait can solve a Model and produce a Solution. This trait provides a consistent interface across different solver implementations, such as simplex, interior point, branch-and-bound, or lexicographic solvers.

let mut model = Model::new();
// ... build model variables, constraints, objective ...

let mut solver = DummySolver::new(&model);
let result: Result<_, SolveError> = solver.solve();
match result {
    Ok(solution) => println!("Optimal solution: {}", solution.objective_value.unwrap_or(0.0)),
    Err(e) => println!("Solver error: {}", e),
}
