Expand description

Cardinality constraint encoder

Implementations§

impl CardinalityEncoder

pub fn encode_at_most_k(solver: &mut Solver, lits: &[Lit], k: usize) -> bool

Encode an at-most-k constraint: sum(lits) <= k

§Arguments

solver - The SAT solver
lits - The literals in the constraint
k - The upper bound

Returns true if the constraint was successfully encoded

pub fn encode_at_least_k(solver: &mut Solver, lits: &[Lit], k: usize) -> bool

Encode an at-least-k constraint: sum(lits) >= k

Equivalent to: at-most-(n-k) of the negations

pub fn encode_exactly_k(solver: &mut Solver, lits: &[Lit], k: usize) -> bool

Encode an exactly-k constraint: sum(lits) == k
