A target gap to be reached
  Type: double
  Default value: 0
  Minimum value: 0
  Maximum value: Infinity

A target gap to be reached. As soon as the tuner has found parameter settings that allow Gurobi to reach the target gap for the given model(s), it stops trying to improve parameter settings further. Instead, the tuner switches into the cleanup phase (see TuneCleanup parameter).

For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
