I had this definition
IloArray<IloIntVarArray> TurneroCalculado(env, simu.plantilla.size());
for (i = 0; i < simu.plantilla.size(); i++) {
TurneroCalculado[i] = IloIntVarArray(env, simu.numDiasTurnero, 0, numDeTurnos-1);
for (d = 0; d < simu.numDiasTurnero; d++) {
TurneroCalculado[i][d] = IloIntVar(env);
}
}
and I thought I was setting the min and max of the TurneroCalculado[i][d] variables from 0 to numDeTurnos-1. When I changed to ...
IloArray<IloIntVarArray> TurneroCalculado(env, simu.plantilla.size());
for (i = 0; i < simu.plantilla.size(); i++) {
TurneroCalculado[i] = IloIntVarArray(env, simu.numDiasTurnero, 0, numDeTurnos-1);
for (d = 0; d < simu.numDiasTurnero; d++) {
TurneroCalculado[i][d] = IloIntVar(env, 0, numDeTurnos - 1);
}
}
is not giving those numbers
Still too slow but at least not giving those numbers. Thanks

Hi,
do you have unbounded decision variable such as
dvar int x;
that you could turn into
dvar int x in 0..20;
in order to make the search space smaller ?

Subject: Understanding log file
I am trying to debug my model because it is taking a long time without getting a solution and when I look at the log file I can see very large numbers that I don´t know where they come from. Are these large numbers caused by an error in the model (the small numbers are coherent with some of my variable possible values)? If so, is there any way that helps me troubleshooting the error (knowing which constraint is coming from)?
The model is done with C++ API. If needed I could provide the code although it's a bit long. Thanks
