C++ (Cpp) SatSolver::addXorCNF Examples

Example #1

File: satTest.cpp Project: ShannonKuo/Candy-Game

int main()
{
   initCircuit();

   SatSolver solver;
   solver.initialize();

   //
   genProofModel(solver);

   bool result;
   // k = Solve(Gate(5) ^ !Gate(8))
   Var newV = solver.newVar();
   solver.addXorCNF(newV, gates[5]->getVar(), false, gates[8]->getVar(), true);
   solver.assumeRelease();  // Clear assumptions
   solver.assumeProperty(newV, true);  // k = 1
   result = solver.assumpSolve();
   reportResult(solver, result);

   cout << endl << endl << "======================" << endl;

   // k = Solve(Gate(3) & !Gate(7))
   newV = solver.newVar();
   solver.addAigCNF(newV, gates[3]->getVar(), false, gates[7]->getVar(), true);
   solver.assumeRelease();  // Clear assumptions
   solver.assumeProperty(newV, true);  // k = 1
   result = solver.assumpSolve();
   reportResult(solver, result);
}

// If they are equivalent, return true 
// else return false
