[−][src]Struct optimization_engine::constraints::FiniteSet
A finite set, $X = \{x_1, x_2, \ldots, x_n\}\subseteq\mathbb{R}^n$, given vectors $x_i\in\mathbb{R}^n$
Implementations
impl<'a> FiniteSet<'a>
[src]
pub fn new(data: &'a [&'a [f64]]) -> Self
[src]
Construct a finite set, $X = \{x_1, x_2, \ldots, x_n\}$, given vectors $x_i\in\mathbb{R}^n$
Parameters
- data: vector of vectors (see example below)
Example
use optimization_engine::constraints::*; let data: &[&[f64]] = &[ &[1.0, 1.0], &[0.0, 1.0], &[1.0, 0.0], &[0.0, 0.0], ]; let finite_set = FiniteSet::new(data);
Panics
This method will panic if (i) the given vector of data is empty and (ii) if the given vectors have unequal dimensions.

impl<'a> Constraint for FiniteSet<'a>
[src]
fn project(&self, x: &mut [f64])
[src]
Projection on the current finite set
Traverses the elements of the vector, computes norm-2 distances
to each element, and updates the given vector x
with the closest
element from the finite set.
Parameters
x
: (input) given vector, (output) projection on finite set
Example
use optimization_engine::constraints::*; let data: &[&[f64]] = &[ &[0.0, 0.0], &[1.0, 1.0], ]; let finite_set = FiniteSet::new(data); let mut x = [0.7, 0.6]; finite_set.project(&mut x); // compute projection
Panics
