FFCG: Effective and Fast Family Column Generation for Solving Large-Scale Linear Program

AAAI 2025technical

Column Generation (CG) is an effective and iterative algorithm to solve large-scale linear programs (LP). During each CG iteration, new columns are added to improve the solution of the LP. Typically, CG greedily selects one column with the most negative reduced cost, which can be improved by adding…
