How tight is the corner relaxation?
Given a mixed-integer linear programming (MILP) model and an optimal basis of the associated linear programming relaxation, the Gomory's corner relaxation is obtained by drop...

How Well Can Primal-Dual and Local-Ratio Algorithms Perform?
We define an algorithmic paradigm, the stack model, that captures many primal-dual and local-ratio algorithms for approximating covering and packing problems. The stack model is ...

Foundations for Virtual Types
Virtual types have been proposed as a notation for generic programming in object-oriented languages—an alternative to the more familiar mechanism of parametric classes. The trade...
