I am a recent user of coliop / cmpl codes. I am wondering if I could get some assistance in how you can deduct a constant from the optimized objective function to get, say for example net loss. Is there any way in which you can actually use the optimized value of objective function (obtained after solving) for any further calculation. The manual does not provide much info. Could someone help please????</div><div style="color: rgb(0, 0, 0); font-size: 13.3333px;
