Trait optimization::Summation

pub trait Summation: Function {
    fn terms(&self) -> usize;
    fn term_value(&self, position: &[f64], term: usize) -> f64;

    fn partial_value<T: IntoIterator<Item = I>, I: Borrow<usize>>(
        &self, 
        position: &[f64], 
        terms: T
    ) -> f64 { ... }
}

Defines a summation of individual functions, i.e., f(x) = ∑ᵢ fᵢ(x).

Required Methods

fn terms(&self) -> usize

Returns the number of individual functions that are terms of the summation.

fn term_value(&self, position: &[f64], term: usize) -> f64

Comptues the value of one individual function indentified by its index term, given the position x.

Provided Methods

fn partial_value<T: IntoIterator<Item = I>, I: Borrow<usize>>(
    &self,
    position: &[f64],
    terms: T
) -> f64

Computes the partial sum over a set of individual functions identified by terms.
