Struct CircuitSAT 

pub struct CircuitSAT { /* private fields */ }

The Circuit SAT problem.

Given a boolean circuit, find variable assignments that satisfy all circuit constraints.

Example

use problemreductions::models::formula::{CircuitSAT, BooleanExpr, Assignment, Circuit};
use problemreductions::{Problem, Solver, BruteForce};

// Create a simple circuit: c = x AND y
let circuit = Circuit::new(vec![
    Assignment::new(
        vec!["c".to_string()],
        BooleanExpr::and(vec![BooleanExpr::var("x"), BooleanExpr::var("y")])
    ),
]);

let problem = CircuitSAT::new(circuit);
let solver = BruteForce::new();
let solutions = solver.find_all_satisfying(&problem);

// Multiple satisfying assignments exist
assert!(!solutions.is_empty());
