用java在cplex中添加表达式

import ilog.concert.*;
import ilog.cplex.*;

public class Main {
    public static void main(String[] args) {
        try {
            IloCplex cplex = new IloCplex();
            // 在这里添加表达式
            // ...
            cplex.end();
        } catch (IloException e) {
            e.printStackTrace();
        }
    }
}

IloNumVar x = cplex.numVar(0, Double.MAX_VALUE, "x");
IloNumVar y = cplex.numVar(0, Double.MAX_VALUE, "y");

IloLinearNumExpr expr = cplex.linearNumExpr();
expr.addTerm(1.0, x);
expr.addTerm(2.0, y);

IloRange range = cplex.addGe(expr, 10.0);

cplex.solve();

double[] varValues = cplex.getValues(x, y);
double objectiveValue = cplex.getObjValue();
