示例1: createModel
TEST(solver_interface, setup_problem) {
ModelPtr solver = createModel(SOLVER_GUROBI);
vector<Var> vars;
for (int i=0; i < 3; ++i) {
char namebuf[5];
sprintf(namebuf, "v%i", i);
vars.push_back(solver->addVar(namebuf));
}
solver->update();
AffExpr aff;
cout << aff << endl;
for (int i=0; i < 3; ++i) {
exprInc(aff, vars[i]);
solver->setVarBounds(vars[i], 0, 10);
}
aff.constant -= 3;
cout << aff << endl;
QuadExpr affsquared = exprSquare(aff);
solver->setObjective(affsquared);
solver->update();
LOG_INFO("objective: %s", CSTR(affsquared));
