        Hi,
        
        I think that I found a BUG.
        
        LP problem
        
        
        Maximize
        obj: + 3 Lanac_1 + 5 Lanac_2 + 4 Lanac_3 + 4 Lanac_4 + 3 Lanac_5
        
        Subject To
        C6: + Lanac_5 + Lanac_3 + Lanac_1 <= 1000
        C7: + Lanac_3 + Lanac_2 + Lanac_1 <= 560.5
        C13: + Lanac_3 + Lanac_2 <= 2500
        C12: + Lanac_4 + Lanac_2 <= 855.2
        C15: + Lanac_4 + Lanac_2 <= 800
        C16: + Lanac_4 + Lanac_2 <= 1000
        C14: + Lanac_5 + Lanac_3 <= 700
        C11: + Lanac_5 + Lanac_4 <= 254.8
        
        Bounds
        200 <= Lanac_1 <= 560.5
        200 <= Lanac_2 <= 560.5
        200 <= Lanac_3 <= 560.5
        200 <= Lanac_4 <= 254.8
        200 <= Lanac_5 <= 254.8
        
        End
        
        For all my variables I'm getting 200 as a result which is not
        correct if we look at constraint C7 or C11:
        
        C7: + Lanac_3 + Lanac_2 + Lanac_1 <= 560.5
        
        600 is not less than 560.5
        

Regards,
Fehim.
