[−][src]Trait cobyla::CstrFn

pub trait CstrFn: Fn(&[f64]) -> f64 { }

A trait to represent constraint function which should be positive eventually
A trait representing aa constraint function.

An constraint function takes the form of a closure f(x: &[f64]) -> f64 The algorithm make the constraint positive eventually.

For instance if you want an upper bound MAX for x, you have to define the constraint as |x| MAX - x. Conversly for a lower bound you would define |x| x - MIN

  • x - n-dimensional array
