Module auto 

Automatic solver selection.

Provides intelligent method selection based on problem characteristics.

Usage

use numra_ode::{OdeProblem, auto_solve, SolverOptions};

let problem = OdeProblem::new(
    |_t, y: &[f64], dydt: &mut [f64]| { dydt[0] = -y[0]; },
    0.0, 1.0, vec![1.0],
);
let options = SolverOptions::default();
let result = auto_solve(&problem, 0.0, 1.0, &[1.0], &options).unwrap();
assert!(result.success);

Selection Strategy

• Non-stiff problems: Uses Tsit5 (efficient, accurate, FSAL)
• Moderately stiff: Uses Esdirk54 (L-stable, good efficiency)
• Very stiff: Uses BDF or Radau5 (high stiffness handling)
• High accuracy: Uses Vern8 (8th order accuracy)
