Hi,
Are the variables shown in this screen shot defined as integer variables? I would check this to start with. It is also important to know how the run termianted, solver status, if a feasible solution was found etc..
Even if they are integers/binary, it is possible that you see a non-integer value and the reason is mentioned in the documentation in the following link under sections binary variables and integer variables:
https://www.gams.com/37/docs/UG_Languag ... eVariables
On a side note, if the variables you show are integers, then I notice that you don't have any upper bound on these variables. This can significantly affect the difficulty of your problem. It is always a good idea to provide a realistic upper bound to help the solver.
