Struct MountainPassConfig 

pub struct MountainPassConfig {
    pub a: Vec<f64>,
    pub b: Vec<f64>,
    pub estimated_pass_level: f64,
    pub path_samples: usize,
}

Configuration for mountain pass detection.

Fields

a: Vec<f64>

Two base points a, b (distinct).

b: Vec<f64>

estimated_pass_level: f64

Estimated mountain pass level c = inf_{γ} max_{t} f(γ(t)).

path_samples: usize

Number of sample points on path.

Implementations

impl MountainPassConfig

pub fn new(a: Vec<f64>, b: Vec<f64>, path_samples: usize) -> Self

Create a new mountain pass configuration.

pub fn estimate_pass_level(&mut self, f: &impl Fn(&[f64]) -> f64) -> f64

Estimate mountain pass level via straight-line path γ(t) = (1-t)a + tb.

pub fn has_mountain_pass_geometry(&self, f: &impl Fn(&[f64]) -> f64) -> bool

Check mountain pass geometry: f(a) < c, f(b) < c, and some x on path achieves c.
