The behavioural intelligence can be seen as a mixture of flexibility, robustness and adaptiveness of behaviour. This mixture is however the key idea of developing today's technical systems which use the Organic Computing (OC) concept. The Organic Computing initiative uses life-like properties such as self-organisation, self-optimisation and selfconfiguration towards building those systems as flexible, robust, and adaptive systems. Robust system shall behave or act appropriately according to situational needs. But this is not guaranteed in novel systems which have their complexity and whose environment is changing dynamically. In this paper, a new concept is investigated to keep a multi-agent system robust when deviations occur in the system behaviour.This concept introduces a robust hybrid central/self-organizing muti-agent system solving the conflict between a central planning algorithm and the autonomy of the agents. Here, the autonomy is recognized as a deviation from the plan of the central algorithm, if the agents are not respecting this plan. The scenario used in this work is a traffic intersection without traffic lights. This scenario offers a lot of cases that can be used to verify the new investigated concept.
Nowadays, micro-programming of machines becomes more common. It is a technique used in several fields such as Computer Engineering. Here it is worth mentioning that micro-programming is employed throughout the design process. As well, designing the control unit of digital computers needs micro-programming, which is more complex than assembly languages. In this field, micro-programs can be written as sequences of micro-instructions. In this context, distinguished teaching of micro-programming of machines requires a suitable and carefully chosen Computer Simulation Tool (CST). This research designs a computer hardware project that introduces a special simulator achieving an easy-to-use microprogramming environment and a user-friendly simulation tool. This tool presents a visualization environment in order to display the execution behaviour of microprograms. It is a model/tool designed as a java program to ensure platform independence. This paper presents the Minimax simulator, which is used in the Minimax project. This project is a part of a hardware practical course. Therefore, it is a simulator for microprogramming and hardware simulation. As a result, this simulator facilitates the process of micro-programming significantly enabling students to understand easily how a computer works. Here, two formal measures and metrics were presented to assess the implemented program, the execution time and the program length. Other results of this study showed how self-organized group work and project management can be accomplished.
Communication protocols are used in telecommunication systems. These protocols are defined as rules, which enable the entities of communicating systems to transfer information usually as packages. Additionally, each standard communication protocol has uniquely-defined structure and consequently a special pattern of network packets. Here, it is worth mentioning that communication protocols are implemented in different ways, in the system software layer or in hardware layer (silicon chipsets). This paper presents the implementation of a special communication protocol called "Packet Analysis", which is used in the Hardware project "Minimax machine". This implementation is a software that can be written using a special simulator "Minimax simulator", which is the target execution environment. That simulator was successfully developed for micro programming and hardware simulations. In this regard, this study develops an algorithm that represents a step toward simulating communication protocols using micro-programming. The flow chart designed here gives an overview of how the "Packet Analysis" algorithm works (designed protocol), which in turn describes all steps in details. As a result, the entire system of this research paper was implemented and tested with various input values. Additionally, the implemented proposed solution (implemented protocol) was evaluated by two metrics (quantitative measures) using test-benches so that its statistics will be trustworthy for research. Other results of this study showed that there is a lot of scope for optimization in the solution presented in this research paper. This leads in turn to optimize the proposed implementation and to consider implementation alternatives.
