Binary Variables Definition

[Yasmine]

Hello,

I have a decision variable (x) that should be outputted from an optimization problem

This variable should be outputted as binary, taking only the values of "0" OR "1"

How can I define that at SAS proc iml?

As I can't find a syntax that puts that as a condition

In addition, I tried the below equation to be added to the constraints of my optimization problem, which ends up with the same meaning, but it gave no results

x*(1-x)=0

Please help

this is very urgent and I have due date with very limited timingssssssssssss

thanks a lot

Since this is an IML question you will likely get a quicker answer posting there than the general discussions.
