Struct CofactorIso 

Source 
pub struct CofactorIso {
    pub cap: usize,
}
Expand description

Merge cofactors that are CNF-isomorphic (any relabeling + polarity flip) — the strongest decidable rung, the symmetry that need not live in the instance. cap bounds the brute force.

Fields§

§cap: usize

Trait Implementations§

Source§

impl Congruence for CofactorIso

Source§

fn name(&self) -> &str

A short label for reporting ("identity", "Bn", "AGL", "cofactor-iso").
Source§

fn canonicalize(&self, clauses: &CanonClauses) -> (CanonClauses, Twist)

The canonical representative of clauses’s class, and the twist mapping clauses onto it (i.e. apply_twist(clauses, twist) == representative).
