Hi Dileep,

That did the trick, thanks for your help!

## Jackson,

Write your constraint as follow,

Const1(i) … z(i) =l= y ;

Thanks for the response.

I went ahead with what you said my constraint is:

Const1 … z(i) =l= y ;

And I’ve already defined the set i.

Now I get a new error that states: Uncontrolled set entered as constant.

both my z(i) and y are decision variables.

What am I doing wrong here?

Thanks,

Jackson

Hi

Just define a set i:

set i /1,2,3,4/

(you can replace 1,2,3,4 with anything you want). And then write the equation as

Eq(i)…

x(i)=l=10;

the above reads for each i in the set one equation:

x(1)= 30;

It defines a set of N constraints that have similar structure.

best regards.

Hi,

I’m currently trying to figure out the syntax similar to “forall” in AMPL. I want to create a constraint that checks each x(i) in my model, how would I do this?

Thanks,

Jackson
