Interior Point Methods for Nondifferentiable OptimizationWe describe the analytic center cutting plane method and its relationship to classical methods of nondifferentiable optimization and column generation. Implementations issues are also discussed, and current applications listed.

Convergent Stepsize Rules for Subgradient Optimizationto estimates of the optimal value. We establish global convergence in objective values for simple level controls without requiring that the feasible set be compact. Our framework may handle accelerations based on “cheap” projections, surrogate constraints, and conjugate subgradient techniques.

Semi-Automatic Generation of Worst Case Instancesle due to the expected exponential running time in the problem’s size. Therefore, heuristics like local search methods are applied to these problems which generate sub-optimal solutions in polynomial time.
