Hi,

Is there a way (in a main script) to find out if a variable is defined in a model ?

Something like model.variableExists("x")

Thanks in advance for your help

Hi,

what I would do : export into mps and then parse

int nbKids=300;
float costBus40=500;
float costBus30=400;
 
dvar int+ nbBus40;
dvar int+ nbBus30;
 
minimize
 costBus40*nbBus40  +nbBus30*costBus30;
 
subject to
{
 40*nbBus40+nbBus30*30>=nbKids;
}
 
main
{
thisOplModel.generate();
cplex.exportModel("c:/zoo.mps");
}

gives

zoo.mps

* ENCODING=ISO-8859-1
NAME          zooEnglish
ROWS
 N  obj     
 G  c1      
COLUMNS
    MARK0000  'MARKER'                 'INTORG'
    nbBus40   obj                           500
    nbBus40   c1                             40
    nbBus30   obj                           400
    nbBus30   c1                             30
    MARK0001  'MARKER'                 'INTEND'
RHS
    rhs       c1                            300
BOUNDS
 LI bnd       nbBus40   0
 LI bnd       nbBus30   0
ENDATA

regards

So, no simple way :(
BTW, I could parse directly the mod-file ...
