Enum Quadrature 

pub enum Quadrature<const D: usize> {
    Sobol {
        num_points: usize,
        seed: u64,
    },
    LatinHypercube {
        num_points: usize,
        seed: u64,
    },
    GaussLegendre {
        points_per_axis: usize,
    },
}

Quadrature scheme for discretising the prior integral into Q sample points.

Variants

Sobol

Sobol low-discrepancy QMC on [0,1]^D, transformed to the prior support. Convergence rate is O(log(N)^D / N) for smooth integrands — much faster than Monte Carlo’s O(1/sqrt(N)).

Fields

num_points: usize

Number of quadrature points. Powers of two are most efficient for Sobol.

seed: u64

PRNG seed (used only for the Owen scrambling when enabled; deterministic with the same seed).

LatinHypercube

Latin-Hypercube sampling — better tails than pure random, simpler than Sobol.

Fields

num_points: usize

Number of quadrature points.

seed: u64

PRNG seed for reproducibility.

GaussLegendre

Gauss–Legendre tensor product over an axis-aligned box. The total point count is points_per_axis^D. Exact on polynomials up to degree 2*points_per_axis - 1 along each axis. Only valid when the prior has finite, axis-aligned support — i.e. Prior::Uniform (and effectively Prior::Custom if you accept the bounding-box restriction).

Fields

points_per_axis: usize

Nodes per axis. Total points = points_per_axis.pow(D as u32).
