We study several problems related to finding reset words in deterministic finite automata. In particular, we establish that the problem of deciding whether a shortest reset word ha...
This paper introduces a new notion related to the traveling salesperson problem (TSP) -the notion of the TSP ratio. The TSP ratio of a TSP instance I is the sum of the marginal va...

The present paper deals with the problem of calculating queue length distributions in a polling model with (exhaustive) k-limited service under the assumption of general arrival, ...
In this paper we consider a single-server cyclic polling system. Between visits to successive queues, the server is delayed by a random switch-over time. The order in which custom...
