A Self-Adaptive Approach to Representation Shifts in Cultural Algorithms
The paper describes how a formal model of selfadaptation [Angeline, 1995] can be expressed in terms of Cultural Algorithms. A particular form of self-adaptation concerns the shifting of the representational bias used to described the set of learned beliefs within the Cultural Algorthms. A version of Cultural Algorithms with the ability to shift its representational bias was used to solve the Ro...
متن کاملA theory of modern cultural shifts and meltdowns.
Many cultural attributes such as adornment, language slang, mannerisms and rituals are thought to have little or no influence on individual survival and reproduction, functioning rather as markers of cultural identity that promote group cohesion. Here, I show that if cultural markers are under weak selection and subject to loss or substitution, then the breakdown of cultural cohesiveness may pr...
متن کاملCOUNTEREXAMPLES IN CHAOTIC GENERALIZED SHIFTS
In the following text for arbitrary $X$ with at least two elements, nonempty countable set $Gamma$ we make a comparative study on the collection of generalized shift dynamical systems like $(X^Gamma,sigma_varphi)$ where $varphi:GammatoGamma$ is an arbitrary self-map. We pay attention to sub-systems and combinations of generalized shifts with counterexamples regarding Devaney, exact Dev...

متن کاملAlmost specification and renewality in spacing shifts
Let $(Sigma_P,sigma_P)$ be the space of a spacing shifts where $Psubset mathbb{N}_0=mathbb{N}cup{0}$ and $Sigma_P={sin{0,1}^{mathbb{N}_0}: s_i=s_j=1 mbox{ if } |i-j|in P cup{0}}$ and $sigma_P$ the shift map. We will show that $Sigma_P$ is mixing if and only if it has almost specification property with at least two periodic points. Moreover, we show that if $h(sigma_P)=0$, then $Sigma_...
