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 ...
The computer simulation control problem can be splitted in two parts, namely a local control problem and a global control problem. The local control de nes the \behavior" of ...
Lattice graphs are used as underlying data structures in many statistical processing systems, including natural language processing. Lattices compactly represent multiple possible...
