Colony: An Artificial Life Model for Active Autonomous Objects

Appropriate aids on top of the primitive object-oriented model will help promote better understanding of the semantics of applications and allow us to focus better on the various aspects of given problems. This study focuses on the exploration of a design model and the corresponding programming framework for the modelling and implementation of applications involving active autonomous objects based on the object technology. The proposed design model is an artificial life model based on the colony phenomenon in nature. This model can naturally be mapped onto an object-oriented implementation. The colony model favours a predicate-based object communication/coordination pattern as opposed to the navigational message-passing paradigm seen in programming languages such as C+ +. The proposed model is particularly appealing to us, for it presents a unifying conceptual design model and programming framework for a wide class of applications including neural networks, genetic algorithms and fuzzy expert systems. The ideas presented are illustrated through a genetic algorithm problem.     

External relationships of objects

External relationships of objects represent semantic dependencies between objects that enable inter-object communication and augment the services the objects provide with role-specific behaviors. Most of the object-oriented design methodologies support the notion of external relationships at the conceptual level, but OO programming languages have no language construct to directly implement the external relationships, which are implemented as containment relationships with embedded pointers resulting in the semantics of the relationships being buried in code. Moreover, object-oriented programming languages lack a mechanism to allow a dynamic classification of objects according to the roles they play in external relationships. This paper describes a technique to treat an external relationship as a conceptually useful abstraction at the specification stage and a separately identifiable structure at the implementation stage, by providing a declarative specification and an implementation in C++ with special focus on the implementation of object roles. © 1998 John Wiley & Sons, Ltd.     

Existence dependency: The key to semantic integrity betweenstructural and behavioral aspects of object types

In object-oriented conceptual modeling, the generalization/specialization hierarchy and the whole/part relationship are prevalent classification schemes for object types. This paper presents an object-oriented conceptual model where, in the end, object types are classified according to two relationships only. Existence dependency and generalization/specialization. Existence dependency captures some of the interesting semantics that are usually associated with the concept of aggregation (also called composition or Part Of relation), but in contrast with the latter concept, the semantics of existence dependency are very precise and its use clear cut. The key advantage of classifying object types according to existence dependency are the simplicity of the concept, its absolute unambiguity, and the fact that it enables to check conceptual schemes for semantic integrity and consistency. We will first define the notion of existence dependency and claim that it is always possible to classify objects according to this relationship, thus removing the necessity for the Part Of relation and other kinds of associations between object types. The second claim of this paper is that existence dependency is the key to semantic integrity checking to a level unknown to current object-oriented analysis methods. In other words: Existence dependency allows us to track and solve inconsistencies in an object-oriented conceptual schema     

Visual Zero: A persistent and interactive object-oriented programming environment

In this article, an ongoing research project held in the Computer Science department of the University of Vigo is described. Its main objective is to develop an interactive object-oriented environment, serving as a vehicle for learning object-oriented programming. It currently consists of a virtual machine, an assembler, compilers for two high-level programming languages, and an educational visual programming environment. Its main characteristics are (a) the support of prototype-based object orientation, which is a model of object orientation that actually wraps the class-based model; (b) the support for object persistence, which simplifies all input/output issues to the minimum, and (c) the availability of a new visual programming environment is an invaluable help. We the authors think that the combination of all of these possibilities, will lead to an interesting, useful tool that would be recommended for object-oriented teaching. The whole system has been successfully employed in a number of different courses, allowing students to concentrate on objects and their relationships from the very beginning, and thus helping them to achieve a high degree of knowledge about the object-oriented programming paradigm.

Design dysphasia and the pattern maintenance cycle

Software developers utilize design methods that enable them to manipulate conceptual structures that correlate to programming language features. However, programming languages and the programming paradigms they embody co-evolve over time. Within industrial and academic circles, for example, object-oriented programming has evolved and effectively replaced imperative programming. More recently, many object-oriented languages have assimilated features from other programming paradigms, evolving into multiparadigm languages we refer to as ‘object-oriented plus–plus’ or OO++. This language evolution may weaken the interface between design and implementation, introducing what we call ‘design dysphasia’—a partial disability in the use of a programming language because of incongruous design methods. Software design patterns capture elements of reusable design within a specific context. When the programming languages that are part of pattern context evolve, patterns must adapt to the language change or they may reinforce design dysphasia in the practitioner. We assert that the current ‘capture/recapture’ pattern maintenance model is suboptimal for adapting patterns to language evolution and propose a new ‘capture/modify/recapture’ maintenance cycle as a more effective approach. We then suggest a concrete ‘modify’ phase for current patterns to be adapted to object-oriented based multiparadigm language trends. We present an OO++ Iterator pattern as an example throughout.     

A knowledge-based approach to CIM modeling

This paper discusses issues in building a conceptual modeling approach that has sufficient semantic power to represent the complexities of decision making in CIM systems. To express the information in a conceptual model we make use of an amalgam of powerful paradigms: a hybrid methodology, that integrates the concepts of object-oriented programming, messagepassing semantics, and temporal logic. We further illustrate an example incorporating some of these concepts.     

A New Method of Systemological Analysis Coordinated with the Object-Oriented Design Procedure. I

A formal concept of system as a functional object is proposed. A new method of systemological analysis of complex dynamic systems, conforming to requirements of object-oriented design and based on a formal semantic normative system with an adaptive alphabet, is considered. The base class hierarchy is presented for construction of conceptual models during the process of object-oriented analysis and design.
