This structure contains all the parameters that can be varied during the course of sampling algorithm. Below is the structure exposed, together with its members briefly explained with reference to the above discussion on algorithm's working.

Provided methods

fn iteration_num(&self) -> i32

number of selection rounds

fn set_iteration_num(&mut self, val: i32)

number of selection rounds

fn particles_num(&self) -> i32

number of "perturbed" boxes on each round

fn set_particles_num(&mut self, val: i32)

number of "perturbed" boxes on each round

fn alpha(&self) -> f64

with each new round we exponentially decrease the amount of "perturbing" we allow (like in simulated annealing) and this very alpha controls how fast annealing happens, ie. how fast perturbing decreases

fn set_alpha(&mut self, val: f64)

with each new round we exponentially decrease the amount of "perturbing" we allow (like in simulated annealing) and this very alpha controls how fast annealing happens, ie. how fast perturbing decreases

fn std(&mut self) -> Mat_<f64>

initial values for perturbing (1-by-4 array, as each rectangle is given by 4 values -- coordinates of opposite vertices, hence we have 4 values to perturb)

fn set_std(&mut self, val: Mat_<f64>)

initial values for perturbing (1-by-4 array, as each rectangle is given by 4 values -- coordinates of opposite vertices, hence we have 4 values to perturb)
