Kleene Algebras and Semimodules for Energy Problems (1307.0635v1)
Published 2 Jul 2013 in cs.FL and cs.LO
Abstract: With the purpose of unifying a number of approaches to energy problems found in the literature, we introduce generalized energy automata. These are finite automata whose edges are labeled with energy functions that define how energy levels evolve during transitions. Uncovering a close connection between energy problems and reachability and B\"uchi acceptance for semiring-weighted automata, we show that these generalized energy problems are decidable. We also provide complexity results for important special cases.
