Column generation (CG) models have several advantages over compact formulations, namely, they provide better LP bounds, may eliminate symmetry, and can hide non-linearities in their subproblems. However, users also encounter drawbacks in the form of slow convergency a.k.a. the tailing-off effect...

We present two new methods to stabilize column-generation algorithms for the Temporal Knapsack Problem (TKP). Caprara et al. [Caprara A, Furini F, and Malaguti E (2013) Uncommon Dantzig-Wolfe Reformulation for the Temporal Knapsack Problem. INFORMS J. on Comp. 25(3):560–571] were the first to...
