Struct PolyhedralDomain 

Source 
pub struct PolyhedralDomain {
    pub n: usize,
    pub constraints: Vec<(Vec<f64>, f64)>,
}
Expand description

A lightweight polyhedral domain element: a set of linear inequalities.

Fields§

§n: usize

Number of variables

§constraints: Vec<(Vec<f64>, f64)>

Constraints: each is (coefficients, rhs) meaning sum(a_i * x_i) ≤ b

Implementations§

Source§

impl PolyhedralDomain

Source

pub fn top(n: usize) -> Self

Create the top polyhedron (no constraints).

Source

pub fn add_constraint(&mut self, coeffs: Vec<f64>, rhs: f64)

Add a constraint: coeffs · x ≤ rhs.

Source

pub fn contains(&self, point: &[f64]) -> bool

Check if a point satisfies all constraints.

Source

pub fn num_constraints(&self) -> usize

Number of constraints.
