Type: double
Modifiable: No

Current relative MIP optimality gap; computed as <span>$</span>\vert ObjBound-ObjVal\vert/\vert ObjVal\vert<span>$</span> (where ObjBound and ObjVal are the MIP objective bound and incumbent solution objective, respectively. Returns GRB_INFINITY when an incumbent solution has not yet been found, when no objective bound is available, or when the current incumbent objective is 0.
