set inteps

iLab Assistant

Set the numeric tolerance for accepting a number as an integer in CPLEX. The default value is 0.00001.

Setting MIP integer tolerance¶

Sometimes we will get an infeasible or unbounded result from CPLEX even if the MIP model is solvable. This happens when a binary variable has gotten a value close to 0 or 1, and CPLEX has rounded it to the desired integer value. This small change will in some cases render the modified problem infeasible. By default, CPLEX considers a value integer if the absolute value difference is less than 1.0e-5. To change this, use the command:

set inteps <value>

If command not set: A value of 1.0e-5 will be used

The value set must be between 0 and 0.5.
