Genetic Algorithms and Genetic Programming: Modern Concepts and Practical Applications discusses algorithmic developments in the context of genetic algorithms (GAs) and genetic programming (GP). It applies the algorithms to significant combinatorial optimization problems and describes structure identification using HeuristicLab as a platform for algorithm development. The book focuses on both theoretical and empirical aspects. The theoretical sections explore the important and characteristic properties of the basic GA as well as main characteristics of the selected algorithmic extensions developed by the authors. In the empirical parts of the text, the authors apply GAs to two combinatorial optimization problems: the traveling salesman and capacitated vehicle routing problems. To highlight the properties of the algorithmic measures in the field of GP, they analyze GP-based nonlinear structure identification applied to time series and classification problems. Written by core members of the HeuristicLab team, this book provides a better understanding of the basic workflow of GAs and GP, encouraging readers to establish new bionic, problem-independent theoretical concepts. By comparing the results of standard GA and GP implementation with several algorithmic extensions, it also shows how to substantially increase achievable solution quality.

Research on the patent system and the analysis of patenting activities have become an important field in economics and l)usin(\ss administration. The global demand for patcuit protection has been increasing strongly over the last decades. Institutional changes as well as the broadening of patentable subject matter pose new challenges to patentees and patent offices alike. Especially in Europe, the debate on the patentabihty of biotechnology and softwa- related inventions led to broad public attention to the design of the patent system. Given these developments, it is no wonder that practitioners as well as policy makers are turning to researchers for answers on how to cope with new challenges threatening the patent system. In his dissertation, Stefan Wagner attempts to answer some of these questions. Wagner apphes advanced econometric methods to large-scale data sets which were assembled specifically for the purpose of this thesis. His analysis focuses on various aspects of patent filings, examination and opposition at the European Patent Office. Each of the four self-contained chapters of this book addresses different issues which are important to all stake-holders of the patent system. Wagner closely analyzes institutional features of the European Patent Office, such as the duration of the examination of patent applications, the determinants of the occurrence of patent oppositions and the patentability of business methods under the European Patent Convention. In his concluding chapter he examines the managerial decision between outsourcing patent-related services to patent attorneys or generating them in-house.

Die Qualifikation der Testierfahigkeit ist im Internationalen Privatrecht seit der Kodifikation des Burgerlichen Gesetzbuches umstritten. Diese Untersuchung widmet sich zunachst der Problematik der Anknupfung, wobei der Autor zu einer erbrechtlichen Zuordnung der Testierfahigkeit in den kollisionsrechtlichen Vorschriften des EGBGB gelangt. Daruber hinaus unterbreitet der Verfasser im Hinblick auf den Statutenwechsel einen Normvorschlag, der unter Konkretisierung des bestehenden Gesetzestextes die konsequente Fortfuhrung des im internationalen Testamentsrecht bereits bestehenden Gunstigkeitsprinzips (favor testamenti) verfolgt."
