Accelerating Column Generation in Highly Degenerate Integer Programming Problems with Template Pricing
Template pricing accelerates column generation by maximizing similarity to a template vector while restricting to suitable reduced costs, achieving over 1000x speedups on some degenerate GAP instances and stronger bounds on all 1735 ISA instances.
