We show that (consistently) there is a clone C on a countable set such that the interval of clones above C is linearly ordered and has no coatoms.

The domain of intelligent creatures, systems and entities is suffering today profound changes, and the pace of more than a hundred meetings (congresses, conferences, workshops) per year shows there is a very large community of interest, eager of innovations and creativity. There is now no unanimity and homogeneity of the crowd, no convergence on what concerns scientific or technological goals, ...

We continue the theory of evasion and prediction which was introduced by Blass and developed by Brendle, Shelah, and Laflamme. We prove that for arbitrary sufficiently different f, g ∈ ωω, it is consistent to have eg < ef , where ef is the evasion number of the space ∏ n<ω f(n). For this we apply a variant of Shelah’s “creature forcing”.

We present results from our work on the coevolution of artificial creatures similar to those introduced by Sims [7]. In the present article we are mostly concerned with coevolutionary analysis. Coevolution is prone to complex dynamics which are often difficult to analyse. We introduce an improved analysis method based on Master Tournament matrices [5], which we argue is both less costly to comp...

This paper describes a new layered brain architecture for simulated autonomous and semi-autonomous creatures that inhabit graphical worlds. The main feature of the brain is its division into distinct systems, which communicate through common access to an internal mental blackboard. The brain was designed to encourage experimentation with various systems and architectures. It has so far proven f...
