Emergence is a concept widely used in the sciences, the arts, and engineering. Some effort
has been made to formalize it, but it is used in various contexts with different meanings, and …

In classic formal language and automata theory, grammars and automata were modeling
classic computing devices. Such devices were “centralized”—the computation was …

A formal framework for studying systems made up of a community of agents and their
environment is proposed. The suggested model, technically based on the theory of formal …

We investigate the expressive power of timing restrictions on labeled transition systems. In
particular, we show how constraints on clock variables together with a uniform liveness …

The title above is exactly the title of a monograph [9] published in 1994 by Gordon and
Breach, London. The main aim of the present paper is to present recent notions and results …

Eco-grammar systems (EG systems) have been introduced in [2] for modelling syntactic
properties of ecosystems. In this paper simple EG systems are discussed, which have n …

Informally, we will consider an agent as a sensor/effector system that operates within an
environment and changes states of that environment by acts performed in it. In present days …

In this paper, we investigate simple eco-grammar systems with n agents. The number of
agents which are active at each derivation step depends on the number of steps which have …

We investigate the generative capacity of the so-called conditional tabled eco-grammar
systems (CTEG). They are a variant of eco-grammar systems, generative mechanisms …

In this paper we investigate simple eco-grammar systems with dynamically formed teams of
agents. Three natural conditions for constituting a team, based on the agents' current …
