Function pmcore::routines::expansion::adaptative_grid::adaptative_grid

pub fn adaptative_grid(
    theta: &mut Array2<f64>,
    eps: f64,
    ranges: &[(f64, f64)],
    min_dist: f64,
) -> Array2<f64>

Implements the adaptive grid algorithm for support point expansion.

This function generates up to 2 new support points in each dimension for each existing support point. New support points are symmetrically placed around the original support point, at a distance of eps * (range_max - range_min). If the new support point is too close to an existing support point, or it is outside the given range, it is discarded.

Arguments

• theta - A mutable reference to a 2D array representing the existing support points.
• eps - A floating-point value representing the fraction of the range to use for generating new support points.
• ranges - A slice of tuples representing the range of values for each dimension.
• min_dist - A floating-point value representing the minimum distance between support points.

Returns

A 2D array containing the updated support points after the adaptive grid expansion.
