SolutionSpace

Struct SolutionSpace 

Source
pub struct SolutionSpace {
    pub num_vars: usize,
    pub particular: Vec<bool>,
    pub kernel_basis: Vec<Vec<bool>>,
}
Expand description

The complete solution space of a GF(2) linear system A x = b, in symmetry-broken form: one particular solution x₀ plus a basis of the kernel. Every solution is x₀ ⊕ (a GF(2) combination of the kernel basis), so the entire affine coset — all 2^{n−rank} solutions — is generated from this compressed witness. The kernel is the symmetry group of the solution set (the translations that preserve Ax), x₀ is one witness, and the basis are its generators: this is the exact, polynomial, linear analog of hypercube::model_orbit. The harder the break (the bigger the kernel), the more solutions; an invertible system has a trivial kernel — no symmetry, a unique witness.

Implementations§

Source§

impl SolutionSpace

Source

pub fn count(&self) -> u128

The number of solutions: 2^{dim kernel} (rank–nullity) — the orbit size of the solution coset.

Source

pub fn enumerate(&self) -> Vec<Vec<bool>>

Generate every solution by XORing the particular solution with each subset of the kernel basis — the orbit of x₀ under the kernel’s translation symmetry.
