mod py_objective

module py_objective

Adapter wrapping a Python callable into the Rust Objective<f64> trait. Adapter wrapping a Python callable into the Rust Objective<f64> trait.

The numpy 0.26 crate is built against ndarray 0.16, while the rest of eindir-core uses ndarray 0.17. To avoid an ABI mismatch between the two ndarray copies, we cross the pyo3 boundary as &[f64] / Vec<f64> and reconstruct ndarray 0.17 Array1<f64>` / ArrayView1<f64>` on the Rust side via ``Array1::from_vec / ArrayView1::from.

Functions

fn low_discrepancy_points(low: PyReadonlyArray1<'_, f64>, high: PyReadonlyArray1<'_, f64>, n: usize, skip: u64) -> PyResult<Vec<Vec<f64>>>

Low-discrepancy points scaled to the supplied box bounds.

fn shifted_low_discrepancy_points(low: PyReadonlyArray1<'_, f64>, high: PyReadonlyArray1<'_, f64>, n: usize, skip: u64, seed: u64) -> PyResult<Vec<Vec<f64>>>

Deterministically shifted low-discrepancy points scaled to box bounds.

Structs and Unions

struct PyBounds

pyo3-exposed wrapper around Bounds<f64> constructed from numpy arrays.

Implementations

impl PyBounds

struct PyFPair

pyo3-exposed wrapper around FPair<f64>.

Implementations

impl PyFPair

struct PyObjective

Wraps a Python callable into the Rust Objective<f64> trait so the SA driver loop can call user-defined Python objectives without leaving Rust per evaluation.

When grad_fn is supplied at construction the object also implements Gradient<f64> (native / analytic gradient, Ceres-style). Without a supplied gradient, callers use FiniteDiffGradient explicitly.
