An Effective Deflected Subgradient Optimization Scheme for Implementing Column Generation for Large-Scale Airline Crew Scheduling Problems
(INFORMS, 2008)We present a new deflected subgradient scheme for generating good quality dual solutions for linear programming (LP) problems and utilize this within the context of large-scale airline crew planning problems that arise ... -
Enhancing Lagrangian dual optimization for linear programs by obviating nondifferentiability
(INFORMS, 2007)We consider non differentiable optimization problems that arise when solving Lagrangian duals of large-scale linear programs. Different from traditional subgradient-based approaches, we design two new methods that attempt ...
