Hierarchies and Characterizations of Stateless Multicounter Machines
Abstract. We investigate the computing power of stateless multicounter machines with reversal-bounded counters. Such a machine can be deterministic, nondeterministic, realtime (the...

Robust invariant set theory applied to networked buffer-level control
— A manufacturer producing several items keeps them into safety stocks (buffers) in order to supply an external stochastic demand without interruptions. We consider the classical...
