Quadratic Lyapunov function based Algorithms (QLAs) for stochastic network optimization problems, which are cross-layer scheduling algorithms designed by Lyapunov optimization technique, have been widely used and studied. In this paper, we investigate the performance of using Lyapunov drift and perturbation in QLAs. By analyzing attraction points and utility performance of four variants of OQLA (Original...
Many countries like China are in a dilemma between economic growth and environmental deterioration (e.g., smog weather). Simultaneously, a growing people concern the product's environmental performance along with their improving environment awareness. This paper focuses on the impacts of carbon footprint and low-carbon preference on the production decision of emission-dependent firms in the cap-and-trade...
This paper presents VPGE, an interactive GLR parser generation and debugging system. Its design has been driven by three main concerns: the ability to parse any context free grammar; simplify the parser construction for large legacy systems; visual interactive parser generation and grammar debugging. VPGE is unique in three aspects comparing with the traditional parser generators: a fast GLR parser...
