....functionality and usability perspectives, trying to ensure that our system would work and be used. As a result, our system is both modular and integrated, portable and stationary, complex and simple. 6. 2 Ants and Environments: True complexity lies in the user In The Sciences of the Artificial [40], Herbert Simon uses an ant crawling on a beach as an example of seemingly complex behavior. His ant moves towards a goal, perhaps towards its colony, planning its route with a greedy algorithm. It moves forward, and on encountering 51 an obstacle, chooses the best path around it. In this way, ....

....and action variables. Even very fast exact algorithms cannot solve such large planning problems in a reasonable amount of time. Fortunately, in many such cases we can group the variables in these planning problems into subsystems that interact in a simple manner. As argued by Herbert Simon [20] in Architecture of Complexity , many complex systems have a nearly decomposable, hierarchical structure , with the subsystems interacting only weakly between themselves. In this paper, we represent planning problems using a hierarchical decomposition into local subsystems. In multiagent ....

....systems setting. Minsky uses a society metaphor in his work on the society of mind [36] The notion of social choice is an important element in e.g. the work of Jon Doyle [15] Finally, social metaphors appear 40 also in the works of Fox, Kornfeld and Hewitt, Malone, and Simon ( 20] 27] 34] [57]) concerning organization theory. In this paper we treat the notion of an artificial social system in a relatively narrow sense, and with a particular point of view in mind. We wish to develop a theory to support the design of multi agent environments, and to assist the designer by supplying tools ....

....types of organizational structures. For example, Galbraith [21] has developed a set of paradigms for redesigning an organizational structure to cope with the increased communication caused by uncertainty (such as unexpected events and errorful information) Galbraith draws upon Simon s work [55, 56] that recognized the limited information processing capabilities of humans. Called bounded rationality, this limitation applies to both the amount of environmental (sensory) information that can be effectively used to make decisions and the amount of control that can be effectively exercised. ....

....understand the relationships between operators and the composition of interactions. This model will enable us to organize operators by classifying and taxonomizing the space of possible operations. Herb Simon once said in understanding any 73 phenomenon, the first step is to develop a taxonomy [91]. The inherent value of classification and understanding is that it enables us to isolate the important artifacts for design. In information visualization, an operator framework will allow us to build interaction models for new data domains. While we were motivated by our research in the ....

....and naturally integrates the reasoning mechanism with the learning mechanism. According to AI scientists, learning is defined as a process which involves changes to the content and organization of a system s knowledge enabling it to improve its performance on a particular task or set of tasks [27]. Learning occurs when the system acquires new knowledge from its environment or when it re organizes its current knowledge to make better use of it [8] In the system discussed in this thesis, a modified case can be stored in the case base by appending it to the end of the case instance list. ....

A system is defined through a model and contains, input, output, state, as well as mapping functions from input and state to output. It matters little whether the system is natural or artificial [71]; a system can represent a computer, program, pendulum clock, or a cow. The theme of designing systems of software continued into the field of Software Engineering during the 1970s. Software engineering diverged from systems theory, and yet retains its lineage in the sense that software is a type ....

....function is most appropriate in certain types of systems: Systems that involve many variables, but where the strong interactions between the variables are fairly sparse, so that the decoupling of the influence between variables does not induce an unacceptable loss in accuracy. As argued by Herbert Simon [1981] in Architecture of Complexity , many complex systems have a nearly decomposable, hierarchic structure , with the subsystems of such systems interacting only weakly between them. We selected to try our algorithm on a problem that we believe characterizes this type of structure. The problem ....

This section describes the characteristics of building regulations as design knowledge and introduces some knowledge based systems which address the issue of knowledge representation for building regulations. 1.3. 1 Building Regulations as Design Knowledge One view of design by [Simon 81, Logan Smithers 89, Ganeshan et al. 92, Lawson 90] is as follows. Design is a goal oriented activity that produces a description of an artifact which satisfies a set of certain goals or functional requirements. In order to produce a description of an object which satisfies these goals or ....

Though we have not implemented the strategy on multi cluster structures, a multi level hierarchical system seems rational if the system confronts a problem with large uncertainty[21]. Social organization should emerge out of necessity. 9 2.3. controlling frequency of communication As well as the range, the frequency of multicast affects the performance of the system. Frequency control strategy changes the rate of the update of information. If the information increases ....

....about an operating computer bears any particular relation to the specific nature of the hardware. A computer is an organization of elementary functional components in which, to a high approximation, only the function performed by those components is relevant to the behavior of the whole system. [Si] When discussing computers, Simon mostly referred to hardware systems. Computing at that time followed a strictly algorithmic paradigm, with procedural code executed in batch mode. It was hard if not impossible to visualize today s software systems, which UML was created to model, ones that fit ....

....why they work. But before we explain what GAs are, it might make sense first to consider why they are useful and interesting. 3.1 Why GAs Before we explain some of the Genetic Algorithm s advantages over other optimization techniques, we should define optimization more precisely. Op 1 Simon [36] coined this term, which means good enough, as opposed to strictly optimal. 16 timization is the process of finding, for some objective function f : p , a parameter vector (x 1 ; x 2 ; x p ) such that f(x 1 ; x 2 ; x p ) is as small or as large as possible. Satisficing ....

....events, may actually turn out to be quite good upon its execution. Simon uses the term satisficing to describe solutions that are good enough for approximate models of the the real world. Optimal solutions, on the other hand, are generally attainable only within simplified or imaginary domains [Simon, 1981] . The basis of heuristic search is to satisfactorily solve combinatorial problems while requiring less structure in the problem representation. The issue of producing optimal versus satisficing results in the solution of RCSPs is a common topic in OR, while most AI techniques tend to focus on the ....

....his specific need. This always 7 requires quite some work, and so simulators are often kept as simple as possible. For example they represent a two dimensional environment where creatures can only occupy a location on a discrete grid. However, as it was already stated in 1981 by Herbert Simon [11], the complexity of a behavior depends on the complexity of the studied individual and its surroundings. His famous example describes a scene in which an ant is walking on a beach. Simon notes that the ant s path might be quite complex, but it does not necessarily reflect the complexity of the ....

The motivating factors are the existence of open interactive spaces, and individualization of interactive services. 4 Towards Principles of Information Systems 4. 1 Complex Systems Information systems are a complex systems [26] whose raison d etre is the interactions that it carries out within itself and with its environment. Interactive services that a system provides to its users, results in evolution of the system behavior in time. A snapshot of the system captures its static aspects, such as the database schema, ....
