vValue is sorted into ascending order before ApproximateBestSubset(...) is called.
Currently, after a new best set is found, the final element that was added gets removed from the set, and the inner loop continues to search through the remainder of vValue for a better set. It is however impossible for a better set to be achieved with a later element in vValue: As vValue is sorted in ascending order, any set formed with a later element will be of same size or bigger.
Therefore, the lines 1628 & 1629 are obsolete, and the inner loop should also stop on fReachedTarget.
