Determines how large a 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
