Gamultiobj constraint - Is possible to limit the objective functions?

In my multiobjective optimization problem I've 10 objective functions like this
y(1)=a*x(1)+b*x(2)+c*x(3)+d*x(1)*x(2)
where a,b,c,d are costant.
Is there a way to limit y(1)? For example t<y(1)<p.

Sorry, there is no standard way of limiting the value of an objective. Usually, this can be accomplished via a nonlinear constraint, but gamultiobj does not allow nonlinear constraints.
That said, you might be able to affect things the way you want by setting an appropriate initial range.
Good luck,

I do not understand how you expect to impose the constraint
x(4) = x(1)*x(2)
If the vector x is your decision variables, then you would need a nonlinear equality constraint to impose this constraint. But gamultiobj does not admit nonlinear constraints.

Hello, gamultiobj supports non-linear constraints from version R2014b [1] on.
Best regards, Thomas
