One-parametric analysis of column-oriented linear programs

Larsson, Torbjörn; Quttineh, Nils-Hassan - In: Operations research perspectives 10 (2023), pp. 1-6

A linear optimization problem which is amenable to column generation and contains a single parameter in the objective function is considered. We extend and adapt the standard linear programming column generation scheme to effectively and efficiently solve this problem for all values of the...
