One of the constraints evaluates to a DOUBLE variable

[覃岭]

Hi johan:

when I add a new constraint to my model, following warning is throw out when solving.

x - y <= 60 + 500*(1- z)

x,y ∈R

z∈{0,1}

Warning:One of the constraints evaluates to a DOUBLE variable 

can you give me some indications about it?

Impossible to say without the full code, but you have something like x+y<=x+y+1, or versions of thereof
