Struct LevyFlight 

pub struct LevyFlight {
    pub alpha: f64,
    pub scale: f64,
}

Lévy flight with alpha-stable step lengths.

Fields

alpha: f64

Stability parameter in (0, 2]. Smaller = heavier tails.

scale: f64

Scale parameter controlling typical step size.

Implementations

impl LevyFlight

pub fn new(alpha: f64, scale: f64) -> Self

pub fn step_length(&self, rng: &mut Rng) -> f64

Generate a single step length (absolute value of stable variate).

pub fn step_2d(&self, rng: &mut Rng) -> Vec2

Generate a 2D step: random direction with Lévy-distributed length.

pub fn path_2d(&self, rng: &mut Rng, steps: usize) -> Vec<Vec2>

Generate a 2D path starting at the origin.

pub fn path_2d_from( &self, rng: &mut Rng, start: Vec2, steps: usize, ) -> Vec<Vec2>

Generate a 2D path starting from a given position.

pub fn path_1d(&self, rng: &mut Rng, steps: usize) -> Vec<f64>

Generate a 1D path.

pub fn step_lengths(&self, rng: &mut Rng, count: usize) -> Vec<f64>

Compute step lengths for a path (useful for analysis).
