This text presents a comprehensive introduction to an extended Entity-Relationship model both on a conceptual and on a formal, mathematicallevel. In addition to the primitives given by the data model the text introduces a language for the formulation of constraints in order to restrict database states to consistent ones. The text explains an implementation of the approach chosen in the logic programing language PROLOG and discusses in this context the computational power of the proposedcalculus. The extended Entity-Relationship calculus is used to define the meaning of the relational query...

This book presents two major research results on the fast implementation of graph rewriting systems (GRS). First, it explores the class of so-called UBS-GRS, where the complexity of a rewriting step is linear instead of NP, showing for example that visual programming is possible by UBS graph rewriting. Second, an abstract machine for graph rewriting is defined providing an instruction set sufficient for the execution of GRS.
The basic definitions of GRS in the algorithmic approach are introduced and extended by attribution and control structures to comprise a formalism for an operational...

Stochastic local search (SLS) algorithms enjoy great popularity as powerful and versatile tools for tackling computationally hard decision and optimization pr- lems from many areas of computer science, operations research, and engineering. To a large degree, this popularity is based on the conceptual simplicity of many SLS methods and on their excellent performance on a wide gamut of problems, ranging from rather abstract problems of high academic interest to the very s- ci?c problems encountered in many real-world applications. SLS methods range from quite simple construction procedures and...

The International Conference on Life System Modeling and Simulation (LSMS) was formed to bring together international researchers and practitioners in the field of life system modeling and simulation as well as life system-inspired theory and methodology. The concept of a life system is quite broad. It covers both micro and macro c- ponents ranging from cells, tissues and organs across to organisms and ecologic niches. These interact and evolve to produce an overall complex system whose beh- ior is difficult to comprehend and predict. The arrival of the 21st century has been marked by a...
