ObjBound
| Type: | double |
|---|---|
| Modifiable: | No |
The best known bound on the optimal objective. When solving a MIP model, the algorithm maintains both a lower bound and an upper bound on the optimal objective value. For a minimization model, the upper bound is the objective of the best known feasible solution, while the lower bound gives a bound on the best possible objective.
In contrast to ObjBoundC, this attribute
takes advantage of objective integrality information to round
to a tighter bound. For example, if the objective is known to take an
integral value and the current best bound is 1.5,
ObjBound will return 2.0 while ObjBoundC will
return 1.5.
