Hello Kartik,
I'm looking for the lp or sav file. You can use the following functions to export your model:
· export_as_lp(path=None, basename=None, hide_user_names=False)
· dump_as_lp(path=None, basename=None)
· export_as_sav(path=None, basename=None)
· dump_as_sav(path=None, basename=None)
Regards,

Hi Thierry,
Are you looking for solve log?

Hello Kartik,
It's difficult to answer you with just this description. Could you send me your model?
Best rgards,

Subject: CPLEX Tuning parameter solution not providing same speed up in regular solve
I am using CPLEX Tuning tool in python for my solve. When I run the tuning tool it gives out parameters which are best for my solve: CPXPARAM_Simplex_DGradient 5
CPXPARAM_Read_DataCheck 1
and solve time after tuning is around ~100 secs But when I run the solve with same parameters but without tuning tool solve time is around ~ 600 secs which is weird as these are same parameter tuning tool suggested and used to solve the problem. I do notice that solver log is not showing presolve logs in normal solve though its there in tuning solve. I have tried specifying presolve parameter but of no help. Any suggestion why there could be a discrepancies in both solves?
I am solving lexicographic LP problem which is having 4 levels and CPLEX tuning run on each level and provide the optimal parameters and solution
