The coloring of random graphs has been the subject of intensive research in the last decades. As a result, the asymptotic behaviour of both the chromatic number and the complexity of the colorability problem are quite well understood. However, the asymptotic results give limited help in predicting the behaviour in specific finite cases. In this paper, we consider the application of the usual backtrack...
This paper presents BCAT (Budapest Complexity Analysis Toolkit), a software package to facilitate research on algorithms and computational complexity. BCAT supports the implementation of computational problems, algorithms to solve the problems, and analyzers to analyze the problems. The paper contains details on the software's architecture and the related main design decisions, and reports on the...
The metal screen of new type of medium and high voltage single-core underground cables is comprised of helically applied copper wires embedded in a semiconductive layer. The distribution of current and power among the thin wires is non-uniform in a three-phase system, what can lead to their non-uniform heating, especially during fault conditions. The paper investigates this problem with 2D finite...
The architecture described in this article belongs to a class of dynamic data flow architectures, in which the operand process control significantly affects the performance parameters as well as the system characteristics of the given architecture. The main component of the presented architecture is the multifunctional pipeline unit, which handles processing of data tokens representing the instructions...
