Column generation in the integral simplex method

Rönnberg, Elina; Larsson, Torbjörn - In: European Journal of Operational Research 192 (2009) 1, pp. 333-342

The integral simplex method for set partitioning problems allows only pivots-on-one to be made, which results in a primal all-integer method. In this technical note we outline how to tailor the column generation principle to this method. Because of the restriction to pivots-on-one, only local...
