Toward Civilized Evolution: Developing Inhibitions
نویسندگان
چکیده
Most evolutionary algorithms concerned with a memory of evolution aim at memorizing and reusing the recipes of past successes (e.g. fruitful operators or fruitful mutation directions). The scheme proposed here follows the opposite track, and memorizes the past failures of evolution (unnt oospring) through a virtual individual termed the virtual loser. The underlying metaphor is that oospring should attempt to get further away from the virtual loser than their parents. This is done by a new evolution operator, termed ee-mutation, as an alternative to standard re-combination and mutation. Special attention is paid to adjusting the ee-mutation step size. Experiments on large sized problems validate this approach, and unexpectedly show that a constant ee-mutation step size over a population is desirable.

Interpersonal control, dehumanization, and violence: A self-determination theory perspective
Interpersonally controlling approaches are often used to keep individuals in line, ostensibly in order to create a safer, more civilized society. Ironically, emerging research findings indicate that when people feel controlled, they often respond by behaving in a less civilized, more antisocial manner (Gagné, 2003; Knee, Neighbors, & Vietor, 2001; Mask, Blanchard, Amiot, & Deshaies, 2005; McHos...
متن کاملBlood pressure, sodium intake, and sodium related hormones in the Yanomamo Indians, a "no-salt" culture.
The Yanomamo Indians are an unacculturated tribe inhabiting the tropical equatorial rain forest of northern Brazil and southern Venezuela who do not use salt in their diet. The group therefore presented an unusual opportunity to study the hormonal regulation of sodium metabolism in a culture with life-long extreme restriction of dietary sodium, with parallel observations on blood pressure. Bloo...

Disturbances, organisms and ecosystems: a global change perspective
The present text exposes a theory of the role of disturbances in the assemblage and evolution of species within ecosystems, based principally, but not exclusively, on terrestrial ecosystems. Two groups of organisms, doted of contrasted strategies when faced with environmental disturbances, are presented, based on the classical r-K dichotomy, but enriched with more modern concepts from community...
