In your model, the bounds are the optimal values.

Hi If you fix the upper bound for X with X.UP and the lower bound for Y with Y.LO, those two variables can't get bigger or smaller resp. than these bounds. My guess is that X without restriction would tend to infinity, and Y to minus infinity. Setting whatever value for the bounds will return these ...

Yes, 100% false positives.

No problem. Good you can now work with GAMS again.

Hi As you seem to have Windows Defender (WD), I am almost 100% sure, that this is the problem. Reinstall GAMS but do not run GAMS afterward. Go to the settings of Windows Defender and exclude either the folder or the file from the scan. Start GAMS and closely check your Windows Defender icon/message...

Hi
This might be caused by Windows Defender who puts gams32.exe into quarantine (which happened on my Windows computer. I reported it as false positive two weeks ago).
You have to go to the quarantine and tell Defender that this is not a threat.

Hi Gams does not recognize the option parallelmode as it is solver specific and should be put in an option file. For example, you could add this to your code $echo parallelmode -1 > cplex.opt $echo threads = 8 >>cplex.opt mymodel.optfile=1; where "mymodel" is your model name. Try this and see if the...

Hi A zero value is loaded but GAMS assumes zero for a parameter without a value, so it is only a problem in displaying the values. If you want to display zero values in your listing, you can add EPS to all values of a parameter. The display will then show EPS for the zero values (the special value E...

Hi You can write just one equation: set t /1*100/; FI(i,j,t) =E= It0(i,j)$(t.val = 1) + FI(i,j,t-1)$(t.val > 1) .... If your t set has numbers you can use t.val otherwise you should use ord(t). set t /y1*y100/; FI(i,j,t) =E= It0(i,j)$(ord(t) = 1) + FI(i,j,t-1)$(ord(t)l > 1) .... I hope this helps! C...
