Improved Lagrangean Decomposition: An Application to the Generalized Assignment Problem
Recently two new ways of obtaining improved Lagrangean bounds have been suggested: Lagrangean decomposition and bound improving sequences. In this work we will obtain a Lagrangean approach combining the two ideas mentioned above. We provide theoretical results about the sharpness of the bounds obtai...
