Option file for CPLEX solver
Posted: Thu Aug 24, 2017 4:23 am
Hi all,
I use CPLEX solver to solve the MIP problems, but this solver tends to give the results as below for instance:
MIP Solution: 207.200000 (9469739 iterations, 151607 nodes)
Final Solve: 207.200000 (0 iterations)
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:
epagap=0
epgap=0
epint=0
solnpoolagap=0
solnpoolgap=0
