ILOG CPLEX .NET Reference Manual

Cplex.ControlCallback.GetLB Method 

Returns the current lower bound for the variable var.

protected virtual double GetLB(
   INumVar var
);

Parameters

var
The variable whose current lower bound is being queried.

Return Value

The lower bound for 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.
