Hello,
Since I'm new to aims, I have (I think) a simple question;
How can I do a part of a summation?
So for example; I've got x1, x2, x3, x4 and x5 as my sets. In my mathematical model is one constraint: x5 = 10*x1 + 18*x2. How do I get this in AIMMS?
Hi
Are you able to clarify your question? Or were you able to solve it yourself?
Thanks

Hello
If x1, x2, … x5 are sets, then how do you want to apply a constraint on sets ?
I suppose you mean x1, x2 .. x5 are elements in your set with index i, and you have a variable - say abc(i), and the constraint is
abc(x5) = 10*abc(x1) + 18*abc(x2)
You can write this constraint pretty much like above, just enclose the element names in single quotes.
abc(‘x5’) = 10*abc(‘x1’) + 18*abc(‘x2’)
Is this correct ? If not, can you clarify ?
