A Note on the Relation Between the Generalized GUB-Technique and Dantzig-Wolfe Decomposition

Although the generalized GUBtechnique (GGUB) conceptually is very different from DantzigWolfe decomposition (DW), we show that these methods are very much alike computationally. Our purpose is to provide insight into the close relationship between these methods. The major difference is the number of iterations required for convergence: this issue still remains unresolved.
