GAMS/LOGMIP error - logmip can not handle universe as domain
GAMS/LOGMIP error - logmip can not handle universe as domain
Pleasant greetings.
I am working on a mixed-integer linear programing model with
disjunctions and trying to solve it using GAMS/LOGMIP on refinery
optimization problem. However, I could not overcome the problem posed
by the error message "logmip can not handle universe as domain". I
would greatly appreciate if you could assist me.
Here I provide the codes on LOGMIP part.
Thank you very much indeed for your time and effort!

Re: GAMS/LOGMIP error - logmip can not handle universe as domain
Yeoh,
It seems your are using a GAMS symbol which you declared using the
universe symbol * e.g.
BINARY VARIABLES Y(*);
LogMIP cannot handle such GAMS symbols. Unfortunately, you did not
attach this part of the code so I can't tell you which one it is. You
will have to declare the symbol using a well defined set, e.g.
set a / A, G, H /;
BINARY VARIABLES Y(a);
If this doesn't help, please feel free to send me your code!
