scheduled for committee meetings of a parliament if every committee intends to meet for one day and some members of parliament serve on several committees? How can we find a school timetable of minimum total length, based on the information of how often each teacher has to teach each class?

Or at least a . minor? Will some sufficiently high average degree or chromatic number ensure that one of these substructures

https://doi.org/10.1007/978-3-319-61337-6heorem 1.8.1 solved that problem quite satisfactorily. Let us now ask the analogous question for vertices: when does a graph G contain a closed walk that contains every vertex of . exactly once? If |.| ≥ 3, then any such walk is a cycle: a . of .. If . has a Hamilton cycle, it is called .. Similarly

Advanced Database Features,thers would require very platform-specific details, which are beyond the scope of this book. The goal of this chapter is not to teach you all you need to know about these topics but rather to give you an overview of some of the more advanced features of RDBMSs and where you might use them in your pr

Introduction Time Concepts and Adaptation: Developmental Approachesverse approaches, though, is a basic distinction between studies of fully developed abilities and studies of the developmental process itself. The contributions to this section take the latter approach, and it is the purpose of this introduction to discuss what is distinctive about developmental wor

Newly emerging disciplines such as Information Engineering and Soft Computing are being developed in order to provide the tools required. Conference
