Struct Termination 

pub struct Termination {
    pub max_evaluations: usize,
    pub target: Option<f64>,
}

When an optimizer should stop.

Fields

max_evaluations: usize

Maximum number of objective evaluations.

target: Option<f64>

Optional target: stop as soon as the minimized objective drops to or below this value. None disables early exit.

Implementations

impl Termination

pub fn budget(max_evaluations: usize) -> Self

A pure evaluation budget with no target.

pub fn with_target(self, target: f64) -> Self

Adds an early-exit target (minimized sense).

pub fn target_met(&self, best: f64) -> bool

True once best meets the target, if any.

pub fn reason(&self, evaluations: usize, best: f64) -> Option<StopReason>

The stop reason implied by the current state.
