We consider unconstrained finite dimensional multi-criteria optimization problems, where the objective functions are continuously differentiable. Motivated by previous work of Brosowski and da Silva (1994), we suggest a number of tests (TEST 1–4) to detect, whether a certain point is a locally...

Feedback fluid queues play an important role in modeling congestion control mechanisms for packet networks. In this paper we present and analyze a fluid queue with a feedback-based traffic rate adaptation scheme which uses two thresholds. The higher threshold B <Subscript>1</Subscript> is used to signal the beginning...</subscript>

Given a graph G=(V, E), a set of vertices <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${S \subseteq V}$$</EquationSource> </InlineEquation> covers a vertex <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$${v \in V}$$</EquationSource> </InlineEquation> if the edge-connectivity between S and v is at least a given number k. Vertices in S are called sources. The maximum-cover source location problem, which is a variation of the source location problem,...</equationsource></inlineequation></equationsource></inlineequation>

In this paper, we illustrate that a power series technique can be used to derive explicit expressions for the transient state distribution of a queueing problem having “chemical” rules with an arbitrary number of customers present initially in the system. Based on generating function and...

In this paper we first analyze the stylized facts of electricity prices, in particular, the extreme volatility and price spikes which lead to heavy-tailed distributions of price changes. Then we calibrate Markov regime-switching (MRS) models with heavy-tailed components and show that they...
