[−][src]Struct liblbfgs::LbfgsState

pub struct LbfgsState<'a, E> where
    E: FnMut(&[f64], &mut [f64]) -> Result<f64>,  { /* fields omitted */ }

LBFGS optimization state allowing iterative propagation

Implementations

impl<'a, E> LbfgsState<'a, E> where
    E: FnMut(&[f64], &mut [f64]) -> Result<f64>, [src]

pub fn is_converged(&mut self) -> bool[src]

Check if stopping critera met. Panics if not initialized.

pub fn report(&self) -> Report[src]

Report minimization progress. Panics if not initialized yet.

pub fn propagate(&mut self) -> Result<Progress<'_>>[src]

Propagate in next LBFGS step. Return optimization progress on success. Panics if not initialized.
