Combinatorial optimization is still one of the biggest mathematical challenges if you plan and organize the run-ning of a business. Especially if you organize potential factors or plan the scheduling and sequencing of opera-tions you will often be confronted with large-scaled combinatorial optimization problems. Furthermore it is very difficult to find global optima within legitimate time limits, because the computational effort of such problems rises exponentially with the problem size. Nowadays several approximation algorithms exist that are able to solve this kind of problems satisfactory. These algorithms belong to a special group of solution methods which are called local search algorithms. This article will introduce the topic of simulated annealing, one of the most efficient local search strategies. This article summarizes main aspects of the guest lecture Combinatorial Optimi-zation with Local Search Strategies, which was held at the University of Ioannina in Greece in June 1999.
Dieser Aufsatz wurde anlässlich eines Symposiums in einer Festschrift zu Ehren von Prof. Dr. Heinrich Reichmann veröffentlicht. Es geht um seine Verdienste im Bereich Electronic Government (E-Government) und Verwaltungsreform.
The aim of these lecture notes is to give a quick introduction into neural networks, its algorithms and applications. The notes are not intended as a replacement of a comprehensive textbook.
Die vorliegende Diplomarbeit untersucht die Möglichkeiten, durch Mediation Konflikte bei Geschäftsverhandlungen zwischen unterschiedlichen Ländern und Kulturen zu schlichten.
This paper presents the first empirical test with German establishment level data of a hypothesis derived by Helpman, Melitz and Yeaple in a model that explains the decision of heterogeneous firms to serve foreign markets either trough exports or foreign direct investment: only the more productive firms choose to serve the foreign markets, and the most productive among this group will further choose to serve these markets via foreign direct investments. Using a non-parametric test for first order stochastic dominance it is shown that, in line with this hypothesis, the productivity distribution of foreign direct investors dominates that of exporters, which in turn dominates that of national market suppliers.
General Mental Ability, the Big Five, and several context specific variables are studied in regard to their relationship with two criteria of expatriate success, namely, adjustment and job performance. Interviews and standardized tests were conducted with a sample of 66 German and Austrian expatriates in South Korea. Results show no relationship with General Mental Ability for neither of the two criteria. Hypotheses for Conscientiousness and Emotional Stability were partially confirmed; Extraversion emerged to be negatively related to other-ratings of adjustment. Several context specific variables were found to be related to the criteria. Drawing from the study’s results, recommendations for future studies in the expatriate domain are provided.
PeTAL (Picture Text Annotation Language) is proposed as an XML-standard for digital documents containing text, images, and videos with heavy cross-referencing, esp. from clickable parts of images to other parts of the material. A browser capable of interpreting the PeTAL code shown here is under construction.
