Journal ArticleDOI
TL;DR: Adaptive autonomous agents as mentioned in this paper are systems that inhabit a dynamic, unpredictable environment in which they adapt to the environment in a way similar to humans. But adaptive autonomous agents are not always suitable for humans.
Abstract: One category of research in Artificial Life is concerned with modeling and building so-called adaptive autonomous agents, which are systems that inhabit a dynamic, unpredictable environment in whic...

TL;DR: The paper addresses this Artificial Life route toward AI and reviews some of the results obtained so far.
Abstract: Behavior-oriented Artificial Intelligence (AI) is a scientific discipline that studies how behavior of agents emerges and becomes intelligent and adaptive. Success of the field is defined in terms of success in building physical agents that are capable of maximizing their own self-preservation in interaction with a dynamically changing environment. The paper addresses this Artificial Life route toward AI and reviews some of the results obtained so far.

TL;DR: Our concepts of biology, evolution, and complexity are constrained by having observed only a single instance of life, life on earth as mentioned in this paper, and a truly comparative biology is needed to extend these concepts.

TL;DR: In this article, the authors review results on the evolution of cooperation based on the iterated Prisoner's Dilemma and discuss both in situations where everyone plays against everyone, and for spatial games.
Abstract: We review results on the evolution of cooperation based on the iterated Prisoner's Dilemma. Coevolution of strategies is discussed both in situations where everyone plays against everyone, and for spatial games. Simple artificial ecologies are constructed by incorporating an explicit resource flow and predatory interactions into models of coevolving strategies. Properties of food webs are reviewed, and we discuss what artificial ecologies can teach us about community structure.

TL;DR: In this article, artificial life is defined as those human-made systems that possess some of the key properties of natural life, and artificial systems that serve as models of living systems.
Abstract: Artificial life embraces those human-made systems that possess some of the key properties of natural life. We are specifically interested in artificial systems that serve as models of living system...

Journal ArticleDOI
TL;DR: This paper reviews selected models of morphogenesis with a significant visual component and recommends three new procedural techniques for realistic image synthesis that have shown promise in understanding and simulating morphogenesis.
Abstract: Rapid progress in the modeling of biological structures and simulation of their development has occurred over the last few years. It has been coupled with the visualization of simulation results, which has led to a better understanding of morphogenesis and given rise to new procedural techniques for realistic image synthesis. This paper reviews selected models of morphogenesis with a significant visual component.

TL;DR: The success of Artificial Life depends on whether it will help solving the conceptual problems of biology, and the example is used as an example of the challenge that Artificial Life must meet.
Abstract: The success of Artificial Life (ALife) depends on whether it will help solve the conceptual problems of biology. Biology may be viewed as the science of the transformation of organizations. Yet biology lacks a theory of organization. We use this as an example of the challenge that ALife must meet.

Journal ArticleDOI
TL;DR: A new concept—“open chaos”—is proposed for the instability in a dynamical system with growing degrees of freedom, and it is suggested that studies based on interacting chaotic elements can replace both top-down and bottom-up approaches.
Abstract: The relevance of chaos to evolution is discussed in the context of the origin and maintenance of diversity and complexity. Evolution to the edge of chaos is demonstrated in an imitation game. As an origin of diversity, dynamic clustering of identical chaotic elements, globally coupled each to the other, is briefly reviewed. The clustering is extended to nonlinear dynamics on hypercubic lattices, which enables us to construct a self-organizing genetic algorithm. A mechanism of maintenance of diversity, “homeochaos,” is given in an ecological system with interaction among many species. Homeochaos provides a dynamic stability sustained by high-dimensional weak chaos. A novel mechanism of cell differentiation is presented, based on dynamic clustering. Here, a new concept—“open chaos”—is proposed for the instability in a dynamical system with growing degrees of freedom. It is suggested that studies based on interacting chaotic elements can replace both top-down and bottom-up approaches.

Journal ArticleDOI
TL;DR: Some of the numerous open problems in synthesizing intelligent animal behavior (especially cooperative behavior involving communication) that face the field of AL, a discipline still in its infancy are examined.
Abstract: The tasks that animals perform require a high degree of intelligence. Animals forage for food, migrate, navigate, court mates, rear offspring, defend against predators, construct nests, and so on. ...

TL;DR: RNA landscapes are presented as examples for which an access to phenomena in reality by mathematical analysis and computer simulations is feasible, and new questions concerning stability of structures in evolution can be raised and quantitative...
Abstract: Molecular evolution provides an ample field for the extension of Nature's principles towards novel applications. Several examples are discussed here, among them are evolution in the test tube, nucl...

TL;DR: There is a small, identifiable and growing number of books and conference proceedings available on topics most central to the field, but a few books, such as John von Neumann's visionary Theory ofSelf-ReproducingAutomata (1966), are out of print and can best be found in better libraries.
Abstract: The number of books on biology, evolutionary theory, learning, development, complex systems, neural networks, and other topics relevant to the study of Artificial Life is enormous, of course, but there is nevertheless a small, identifiable and growing number of books and conference proceedings available on topics most central to the field. A few books, such as John von Neumann's visionary Theory ofSelf-ReproducingAutomata (1966), in which he explicitly put forth many key ideas in the field, are out of print and can best be found in better libraries. These older books appear in the reference lists in several of the books whose descriptions follow, and should be consulted whenever
