Hi guys, is there anybody who knows how to simplify the following formula?

dvar float+ Qt[X];

 subject to {

Qt[5]+Qt[6]+Qt[7]+Qt[8]+......+Qt[99]+Qt[100]+Qt[101]+Qt[102] <= 1000;

}

I would like to sum from the Qt[5] to the Qt[102] variable (for instance) without the burden of writing almost 100 variables for just one equation.

Thanks in advance for any help!!

Hi

Qt[5]+Qt[6]+Qt[7]+Qt[8]+......+Qt[99]+Qt[100]+Qt[101]+Qt[102] <= 1000;

can be rewritten into

sum(i in 5..102) Qt[i] <= 1000;
