In this research we tried to apply open-ended evolution to breed controllers for artificial organism which would be able to manifest flocking behaviours. In comparison to the previous work in this area the artificial world created in our system is characterized by significant diversity of organisms. Animals were equipped with double and dynamic sight, which were suggested by other authors in th...

Efficient mass transport through porous networks is essential for achieving rapid response times in sensing applications utilizing porous materials. In this work, we show that open-ended porous membranes can overcome diffusion challenges experienced by closed-ended porous materials in a microfluidic environment. A theoretical model including both transport and reaction kinetics is employed to s...

We explore a homeostatic approach to program execution in computer systems: the “concentration” of computation services is regulated according to their fitness. The goal is to obtain a self-healing effect so that the system can resist harmful mutations that could happen during on-line evolution. We present a model in which alternative program variants are stored in a repository representing the...

Vocal learning in birds is typically restricted to a sensitive period early in life, with the few exceptions reported in songbirds and parrots. Here, we present evidence of open-ended vocal learning in a hummingbird, the third avian group with vocal learning. We studied vocalizations at four leks of the long-billed hermit Phaethornis longirostris during a four-year period. Individuals produce a...

This chapter looks at how a hearer or reader can understand metaphorical discourse, particularly when it is creative. The abilities of the ATT-Meta approach to creative metaphor understanding, implemented in an AI reasoning system, are discussed. A natural extension to metaphor generation is also briefly mentioned. As regards types of creativity, the chapter focusses on how ATT-Meta deals with ...

Pfeiffer contains a population of fractals which has been evolving continuously for more than three years. The animations are developed from embryos using a Lindenmayer grammar (LSystem). These open generative representations potentially allow gene duplication and the evolution of higher order genetic operators and might be a step towards the emergence of social intelligence in swarms of artifi...

A central goal of the field of artificial life is to build evolving systems that capture interesting dynamics of natural systems, producing evolutionary outcomes such as sophisticated navigation behaviors, novel cooperative strategies, complex ecosystems, or major evolutionary transitions, to name but a few. Such “open-ended” systems are sought after for a number of reasons: 1) For artificial l...

In this contribution we will review different conceptions of open-ended evolution and propose our own (RuizMirazo et al., 2008, Biol. & Philos., 23, p.67). Then, we will consider what are the general conditions that would allow such an evolutionary process to take place, with a specific focus on the type of organization that the systems involved should have. It will be argued that a strong ‘dyn...

We report progress on adding affect-detection to a program for virtual dramatic improvisation, monitored by a human director. We have developed an affect-detection module to control an automated virtual actor and to contribute to the automation of directorial functions. The work also involves basic research into how affect is conveyed through metaphor. The relevance of the project to the sympos...

Open-ended activities such as CAD/CAM, VLSI layout and software development require consistent concurrent access and fault tolerance associated with database transactions, but their uncertain duration, uncertain developments during execution and long interactions with other concurrent activities break traditional transaction atomicity boundaries. We propose splittransaction as a new database op...
