I am working on a multiobjective facility location problem. I used MILP for modeling the problem, but I am having difficulties with making the (1 0) constraint, since the gamultiobj. does not support integer constraints. Any idea on how to solve this in the easiest way?

gamultiobj does not allow for integer constraints. Sorry. If you only have a few binary variables, say up to 20 or so, then I think the best thing to do is exhaustive search over the binary variables.

Hi, I want to optimize a (0,1) multiobjective optimization problem using gamultiobj(). I have latest Matlab and optimization toolbox. Does gamultiobj() support integer constraint? If not, is there any way for work around?
Please advise.

No, as I already explained, gamultiobj does not support integer constraints.
