Dear all
I have the problem whose decision variables include forbidden zone. In
other words, its decision variables shouldn’t situate in some areas
such as x1<x<x2 , x3<x<x4. How I can model it in GAMS (except mixed
integer method)?
Thanks in advance

Dear Mohammad
x1,x2,x3 and x4 are parameters (constant) and x is variable.
Thank you for your reply.

dear all
I have a problem with my objective function.my objective function is
Min ∑_j[(2bh∑_i∑_r liYijr (1-q)qr)1/2
my objective function has a power 1/2 and i dont know how show it in gams and my code is
sum(j,((2bhl)**(0.5)(sum((i,r),y(i,j,r)(1-q)(qu(r))))(0.5)))
I want to know is it true or not
