C++ (Cpp) literal_vector::push_back Examples

Example #1

File: dimacs_frontend.cpp Project: greatmazinger/z3

static void track_clause(sat::solver& dst,
                         sat::literal_vector& lits,
                         sat::literal_vector& assumptions,
                         vector<sat::literal_vector>& tracking_clauses) {
    sat::literal lit = sat::literal(dst.mk_var(true, false), false);
    tracking_clauses.set(lit.var(), lits);
    lits.push_back(~lit);
    dst.mk_clause(lits.size(), lits.c_ptr());
    assumptions.push_back(lit);            
}

Example #2

File: cnf_backbones.cpp Project: levnach/z3

static void brute_force_consequences(sat::solver& s, sat::literal_vector const& asms, sat::literal_vector const& gamma, sat::literal_vector& backbones) {
    for (unsigned i = 0; i < gamma.size(); ++i) {
        sat::literal nlit = ~gamma[i];
        sat::literal_vector asms1(asms);
        asms1.push_back(nlit);
        lbool r = s.check(asms1.size(), asms1.c_ptr());
        if (r == l_false) {
            backbones.push_back(gamma[i]);
        }
    }
}

Example #3

File: dimacs.cpp Project: NikolajBjorner/z3

    int     parsed_lit;
    int     var;
    
    lits.reset();

    while (true) { 
        parsed_lit = parse_int(in, err);
        if (parsed_lit == 0)
            break;
        var = abs(parsed_lit);
        SASSERT(var > 0);
        while (static_cast<unsigned>(var) >= solver.num_vars())
