Trait argmin_core::ArgminNextIter

pub trait ArgminNextIter {
    type Parameters: Clone;
    type OperatorOutput;
    type Hessian;

    fn next_iter(
        &mut self
    ) -> Result<ArgminIterationData<Self::Parameters>, Error>;

    fn init(&mut self) -> Result<(), Error> { ... }
}

Main part of every solver: next_iter computes one iteration of the algorithm and init is executed before these iterations. The init method comes with a default implementation which corresponds to doing nothing.

Required Associated Types

type Parameters: Clone

Parameter vectors

type OperatorOutput

Output of the operator

type Hessian

Hessian

Required Methods

fn next_iter(&mut self) -> Result<ArgminIterationData<Self::Parameters>, Error>

Computes one iteration of the algorithm.

Provided Methods

fn init(&mut self) -> Result<(), Error>

Initializes the algorithm

This is executed before any iterations are performed. It can be used to perform precomputations. The default implementation corresponds to doing nothing.
