Hello support team,

I define an integer variable as following:

			GRBVar[][] start = new GRBVar[mach.length][item.length];
			for (int m = 0; m < mach.length; m++) {
				for (int k = 0; k < item.length; k++) {
					start[m][k] = model.addVar(0, 200, 0, GRB.INTEGER, "start" + m + "." + k);
				}
			}

I need to convert the integer variable to the continuous variable without changing in the initial definition.

Would you say that is there any way to cast it?

 

Regards

Omidi. A

  Hi Abbas,

   

  you can change the type of a variable with by settings it's variable type attribute. E.g., start[0][0].set(GRB.CharAttr.VType, GRB.CONTINUOUS).

   

  Best,
