Best possible: 151.594951
Absolute gap: 55.605049
Relative gap: 0.268364

I wanna have zero absolute or relative gap while solving the MIP problems so I used the Optionfile to set the Absoulutegap and relative gap values to zero. The solver, however, still gives results with the absolute and relative gaps more than zero. To me, it seems that I need to set more criteria to get the results with zero gaps. Can anyone help me on this?

P,s: To let you know, here is the criteria I set in the option file:

There are two possibilities: a) GAMS/CPLEX did not process the option file, or b) Cplex terminated on time/iteration/… limit. The log will tell you more. You should find an echo of the options processed and also the reason why Cplex terminated.
