Center node: "modular complexity analysis for term rewriting"
  Abstract: All current investigations to analyze the derivational complexity of term#N#rewrite systems are based on a single termination method, possibly preceded by#N#transformations. However, the exclusive use of direct criteria is problematic#N#due to their restricted power. To overcome this limitation the article#N#introduces a modular framework which allows to infer (polynomial) upper bounds#N#on the complexity of term rewrite systems by combining different criteria.#N#Since the fundamental idea is based on relative rewriting, we study how matrix#N#interpretations and match-bounds can be used and extended to measure complexity#N#for relative rewriting, respectively. The modular framework is proved strictly#N#more powerful than the conventional setting. Furthermore, the results have been#N#implemented and experiments show significant gains in power.
