We introduce a simple open-ended model which describes the emergence of a shared vocabulary. The ordering transition towards consensus is generated only by an agreement mechanism. This interaction defines a finite and small number of states, despite each individual having the ability to invent an unlimited number of new words. The existence of a phase transition is studied, analyzing the conver...

A total of 352 open-ended attributions were obtained in two field studies with volleyball teams and in two lab experiments, all involving team competition. All attributions were classified along the three causal dimensions of locus of causality, stability, and controllability. Attributions were also classified as referring to the self, to teammates, to the team as a whole, or to other factors a...

We have built up an open-ended computerized overview which can give instant access to information because controlled languages (CLs) are of undoubted interest (for safety and economic reasons, etc.) for industry and those willing to create a CL need to be aware of what has already been done. To achieve it, we had a close look at what has been written in the field of CLs and tried to get in touc...

Extended Abstract The term open-ended evolution (“OEE”) is used by the ALife community to refer to the kind of long-term evolutionary dynamics observed in the biosphere. It is generally taken to refer to evolutionary systems which display a continual production of adaptively significant innovations. Furthermore, some authors use the term to imply a sustained increase in complexity and/or divers...

This paper is an effort to begin serious work toward a theory of open-ended evolution (OEE). We begin by defining OEE to mean continued innovation. With this intuitive definition in mind, we closely examine metrics for characterizing behavior of evolutionary systems and argue that none are sufficient for quantifying open-endedness, but there are still avenues to explore. Working from our relati...

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...
