Dear Sir,
Thanks a lot for your reply. I've succesfully overcome the problem by using MINLP solver. thanks so much for your advice.
Kind regards,
fady

equations in MIP model
Dear all,
I am trying a model using binary variables, the constraint equations contain a product of two variables as:
(1- x)*(1-y) =e= 0;
but i get error "Endogenous operands for * not allowed in linear models"
is there any way to solve this or another way rewrite the equation?
thanks

New to GAMS to create simple LP program
Hi all, I'm new to LP and GAMS software. I intend to create a simple linear program the objective function is to minimize the summation of b(i) where b(i) is binary variables (values either 0 or 1) and i is a set from (1 to 57) the constaints are that each b(i) should satisify the following equation...
