Fields

samples: usize

Number of Sobol sequence points to sample for the rationality checks.

seed: u32

Seed for the Sobol sequence scrambling.

strict_monotonicity: bool

Whether to enforce strict monotonicity (U(x + ep) > U(x)).

strict_convexity: bool

Whether to enforce strict convexity (U(midpoint) > min(U(A), U(B))).

epsilon: f64

The small increment used to compute directional changes (e.g. 1e-6).

tolerance: f64

Numerical tolerance for floating-point comparisons (e.g. 1e-9).

continuity_threshold: f64

The threshold marginal utility (d_epsilon -> d_U) for a continuous function.

calc_epsilon: f64

Step size for numerical differentiation (e.g. 1e-7).

calc_tolerance: f64

Tolerance for numerical calculations such as MU/MRS comparisons.
