    Learned Pairwise Deep Dual-Optimal Inequalities for Stabilizing Column Generation

    Zhengzhong Ricky You, Bo Tang, Haoran Liu, Baichuan Mo

    math.OC · cs.LG

    Column generation (CG) is central to many large-scale optimization algorithms, including branch-price-and-cut methods for vehicle routing problems, but unstable dual solutions can substantially slow its convergence. Existing deep dual-optimal inequalities can reduce this instability by restricting the dual space. Their construction, however, typically relies on problem-specific exchange arguments that are difficult to establish for routing...
