Struct EqualityConstraint 

pub struct EqualityConstraint { /* private fields */ }

Represents a linear equality constraint in standard form: ax = b where a is a vector of coefficients and b is a constant.

Implementations

impl EqualityConstraint

pub fn new(coefficients: Vec<f64>, rhs: f64) -> EqualityConstraint

Creates a new equality constraint, normalizing it so the right-hand side is non-negative.

Arguments

• coefficients - Vector of coefficients for the constraint
• rhs - Right-hand side constant value

Example

use rooc::EqualityConstraint;
let constraint = EqualityConstraint::new(vec![2.0, -1.0, 3.0], -4.0);
// Normalizes to: -2x + y - 3z = 4

pub fn coefficients(&self) -> &Vec<f64>

Returns a reference to the coefficient vector.

pub fn coefficients_mut(&mut self) -> &mut Vec<f64>

Returns a mutable reference to the coefficient vector.

pub fn remove_coefficients_by_index(&mut self, indexes: &[usize])

Removes coefficients at the specified indices from the constraint.

Arguments

• indexes - Slice of indices to remove

pub fn coefficient(&self, index: usize) -> f64

Returns the coefficient at the specified index.

Arguments

• index - Index of the coefficient to retrieve

pub fn rhs(&self) -> f64

Returns the right-hand side constant value.

pub fn ensure_size(&mut self, size: usize)

Ensures the coefficient vector has the specified size by padding with zeros if necessary.

Arguments

• size - Required size of the coefficient vector
