Detailed Description

Represents an improper flat (uniform) prior.

Mathematical Formulation A uniform prior assumes constant probability density:

\[ p(\theta) \propto 1 \implies \log p(\theta) = C \]

For convenience, the constant \( C \) is set to 0. All derivatives are zero:

\[ \nabla_i \log p(\theta) = 0 \]

\[ \mathcal{H}_{ij} \log p(\theta) = 0 \]

Implementation Algorithm Returns constant 0.0 for all evaluation, gradient, and Hessian queries.
