Saving some iteration log data generated by CPLEX, as a MIP solver, into parameters. Is this possible?

Post by hossein60 » 2 months ago

Dear all

I want to record some outputs generated by CPLEX such as the iteration number, objective and the associated time so that I can plot some convergence characteristic, for example objective-iteration number, objective-time and objective-number of nodes.
Have you any idea?

Best regards;

Hi,

Have a look at the "miptrace" option of GAMS/Cplex: https://www.gams.com/latest/docs/S_CPLE ... EXmiptrace

Best regards,
Lutz

Hi,

Thanks. But I can not find it in doc/solver/CPLEX maybe because of using GAMS 24.1.
