Hi,

the answer https://www.ibm.com/developerworks/community/forums/html/topic?id=192b7dde-71f0-4170-ab1f-c93b0bf7731e&ps=25

made me realize we often get similar questions.

To set a cplex parameter, one may use a .ops file or an execute block as can be seen at https://www.ibm.com/developerworks/community/forums/html/topic?id=af1033e1-a064-4a7c-89bc-8c4123d73078&ps=25

But sometimes there is no OPL CPLEX settings:

Example:

So what do do ?

First find the Id in cpxconst.h that is in CPLEX_Studio129\cplex\include\ilcplex

In this case:

#define CPXPARAM_Output_CloneLog 1132

And then

execute {

cplex.params[1132] = 1;

}

Of course you should replace 1132 by the identifier you find and 1 by the value you need.
