Trait optimization::Summation1

pub trait Summation1: Summation + Function1 {
    fn term_gradient(&self, position: &[f64], term: usize) -> Vec<f64>;

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

Defines a summation of individual functions fᵢ(x), assuming that each function has a first derivative.

Required Methods

fn term_gradient(&self, position: &[f64], term: usize) -> Vec<f64>

Computes the gradient of one individual function identified by term at the given position.

Provided Methods

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

Computes the partial gradient over a set of terms at the given position.
