- The integral simplex method for set partitioning problems allows onlypivots-on-one to be made, which results in a primal all-integer method. Inthis technical note we outline how to tailor the column generationprinciple to this method. Because of the restriction topivots-on-one, only local optimality can be guaranteed, and to ensureglobal optimality we consider the use of implicit enumeration.
