This paper describes the application of an organic programming language Gaea in programming complex and flexible multi-agent systems. We consider a soccer game as an example. Using organic programming, we can program soccer players in an extended version of a subsumption architecture, called a dynamic subsumption architecture, which is more flexible and efficient than the original one

Almost a year ago, Microsoft has introduced the .NET architecture as a new component-based programming environment, which allows for easy integration of classical distributed programming techniques with Web computing. .NETdefines a type system and introduces notions such ...

SIMULA is a powerful general purpose programming language which includes sophisticated simulation facilities. However, unfamiliarity with the language concepts and the restrictive amount of literature covering the language structure have led to the development of an inertia which has prevented many skilful programmers from using it. This paper presents an attempt towards introducing the concepts of simplicity and expressive power inherent in SIMULA to a wider audience.

Fault-tolerant object-oriented software systems are inherently complex and have to cope with an increasing number of exceptional conditions in order to meet the system's dependability requirements. This work proposes a software architecture which integrates uniformly both concurrent and sequential exception handling. The exception handling architecture is independent of programming language or exception handling mechanism, and its use can minimize the complexity caused by the handling of abnormal behavior. Our architecture provides, during the architectural design stage, the context in which more detailed design decisions related to exception handling are made in later development stages. This work also presents a set of design patterns which describes the static and dynamic aspects of the components of our software architecture. The patterns allow a clear separation of concerns between the system's functionality and the exception handling facilities, applying the computational reflection technique
