    Hi,

    I am going to use lagrangian relaxation for my model. I looked at the example which exists in CPLEX (location-transportation problem) and tried to write my codes according to it. For defining slacks, the example uses the following lines:

     var slack = new Array(thisOplModel.nbCities);
      var temp = new Array(thisOplModel.nbCities);
      var mult = new Array(thisOplModel.nbCities);
      var UB = 0;
      for (var i in thisOplModel.cities) {
        slack[i] = 0.0;
        UB += maxArray(thisOplModel.ship_cost[i]);
        temp[i] = 0.0;
        mult[i] = 0.0;
      } 

    Here, these arrays are one dimensional, but in my problem, I need to define slack, temp, and mult variable as two dimensional arrays. How should I define these variables as two dimensional? (for example slack[i][j], ...)

    Hi

    let me give you an example

    execute
    {

    var x = new Array(10);
      for (var i = 0; i < 10; i++) {
        x[i] = new Array(10);
      }
      x[1][4] = 5;;
      writeln(x[1][4]);
    }
