Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...

Recently in several papers, graphs with maximum neighborhood orderings were characterized and turned out to be algorithmically useful. This paper gives a unified framework for characterizations of those graphs in terms of neighborhood and clique hypergraphs which have the Helly property and whose line graph is chordal. These graphs are dual (in the sense of hypergraphs) to chordal graphs. By us...

Since all graphs in the 1993 DIMACS graph coloring challenge are undirected, each edge should be only counted once. However, in some files each edge is counted once, whereas in others each edge is counted twice; so a systematical check on the DIMACS challenge is made to eliminate the inconsistencies. Besides, the experimental results of a previous paper by Blas et al. counted each violated edge...

A systematic approach for implementing software product lines is more than just a selection of techniques. Its selection should be based on a systematic analysis of technical requirements and constraints, as well as of the types of variabilities, which occur in a particular application domain and are relevant for the planned product line (PL). In addition, each technique should provide a set of...

Abstract. In this paper we present a model for computing thermal stress inside a crystal with facets. Using a systematical perturbation analysis, a semi-analytical thermal stress solution is obtained for constrained directional growth with small lateral heat flux. Our solution can be applied to crystals grown by various growth techniques such as the Czochralski method. The semianalytical nature...

Companies and research institutes are always threatened by rapid technological developments and corporate M&A. They are trying to secure a sustainable competitive advantage using outside knowledge and expertise under open innovation to overcome these shortcomings. As a quantitative and systematical method of selecting virtual team members for open innovation, we present a virtual team formation...

Long-term completely embedded sensor systems offer innovative possibilities for structural health monitoring of concrete structures. Measuring of relevant parameters, e.g., temperature, humidity, or indication of corrosion can be performed with low energy sensors. This allows to implement passive RFID sensor systems without cable connection and battery, which are power supplied exclusively by t...

A critical assessment of the current systematical planning and an in-depth review teaching materials efficiently improve fine educational to benefit developed learning contexts. In some countries, such as Iran, that belong expanding circle, local book writers provide English may ignore sociopragmatic language components, particularly culture. There is a blind spot massive gap in related literat...

The number of word embedding models is growing every year. Most of them learn word embeddings based on the co-occurrence information of words and their context. However, it’s still an open question what is the best definition of context. We provide the first systematical investigation of different context types and representations for learning word embeddings. We conduct comprehensive experimen...

The suicide act of self-strangulation must be distinguished from homicide, which needs objective scene investigation, autopsy and anamnesis in order to elucidate the manner of death. A 54-year-old man was found dead in public hospital small mosque. There was one nylon rope around his neck, tied together with a knot in the front, under the chin, and rope continuing tightly to right ankle support...
