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:
- Behavioral descriptor calculation
- Performance evaluation
- Elite selection and replacement
Performance considerations:
- Memory layout optimization
- Cache utilization
- SIMD operations
