Determines how large a (relative) gap to tolerate in stored solutions.
When this parameter is set to a non-default value, solutions whose
objective values exceed that of the best known solution by more than
the specified (relative) gap are discarded. For example, if the MIP
solver has found a solution at objective 100, then a setting
PoolGap=0.2 would discard solutions with objective worse
than 120 (assuming a minimization objective).
Note: Only affects mixed integer programming (MIP) models
