Evading Predictors with Creatures
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”.
متن کاملEvolving Physical Creatures
One of the prevailing characteristics of natural life is autonomy. The field of Artificial Life has so far addressed the notion of autonomy mostly in terms of power and behavior. In this paper we attempt to extend the notion of autonomy to include also design and fabrication: We claim that not only should artificial creatures be able to operate untethered and without external guidance, but they...

متن کاملClones from Creatures
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.
متن کاملFunctions, Creatures, Learning, Emotion
I propose a conceptual framework for emotions according to which they are best understood as the feedback mechanism a creature possesses in virtue of its function to learn. More specifically, emotions can be neatly modeled as a measure of harmony in a certain kind of constraint satisfaction problem. This measure can be used as error for weight adjustment (learning) in an unsupervised connection...
