Protected Overridable Function GetLB ( _ var As INumVar _ ) As Double |
Parameters
- var
- Type: ILOG.Concert..::..INumVar
The variable whose current lower bound is being queried.
Return Value
The lower bound for the variable var at the current node.
Remarks
This bound
may be different from the bound the variable has in the active model,
since branching or bound strengthening may have been applied to it.
The corresponding solution value from getValue may
violate this bound at a node where a new incumbent has been found
because the bound is tightened when an incumbent is found.
