Technical Deep Dive

Let's examine the Map-Elites implementation in detail:

fn map_elites<T, F>(evaluate: F, dimensions: usize) -> HashMap<Vec<f64>, T>
where
    F: Fn(&T) -> Vec<f64>,
{
    let mut elite_map = HashMap::new();
    // Implementation details...
    elite_map
}

The algorithm's core components:

  1. Behavioral descriptor calculation
  2. Performance evaluation
  3. Elite selection and replacement

Performance considerations:

  • Memory layout optimization
  • Cache utilization
  • SIMD operations
