pub fn lambda_ils_search(
float_cycles: &[f64],
covariance: &[Vec<f64>],
ratio_threshold: f64,
) -> Result<IlsResult, IlsError>Expand description
Correct integer-least-squares via the LAMBDA method (RTKLIB lambda() port).
Finds the true ILS optimum and runner-up for any positive-definite
covariance - no search box, no combinatorial blow-up. Returns the same
IlsResult shape as bounded_ils_search so it is a drop-in: in the
weakly-correlated regime both select the identical integer vector and ratio;
on strongly-correlated geometry only this one is correct.
