const NAME: &'static str

fn next_iter(
    &mut self,
    op: &mut OpWrapper<O>,
    state: &IterState<O>
) -> Result<ArgminIterData<O>, Error>

Computes one iteration of the algorithm.

fn terminate(&mut self, state: &IterState<O>) -> TerminationReason

Checks whether the algorithm must be terminated

fn init(
    &mut self,
    _op: &mut OpWrapper<O>,
    _state: &IterState<O>
) -> Result<Option<ArgminIterData<O>>, Error>

Initializes the algorithm

fn terminate_internal(&mut self, state: &IterState<O>) -> TerminationReason

Checks whether basic termination reasons apply.
