Genetic variability and adaptation to stress
1997Besides an immediate cellular adaptation to stress, organisms can resist such challenges through changes in their genetic material. These changes can be due to mutation or acquisition of pre-evolved functions via horizontal transfer. In this chapter we will review evidence from bacterial genetics that suggests that the frequency of such events can ...

Adapting Representation in Genetic Programming
2004Genetic Programming uses trees to represent chromosomes. The user defines the representation space by defining the set of functions and terminals to label the nodes in the trees. The sufficiency principle requires that the set be sufficient to label the desired solution trees.

PHYLOGENETIC ADAPTATIONS AND THE GENETICS OF PSYCHOSIS
Acta Psychiatrica Scandinavica, 1976There is evidence that many social skills and responses which are of adaptive value are under a significant degree of genetic control. It is suggested that in states of hyper‐arousal these skills are displayed in inappropriate and incomplete forms and that such behaviour constitutes psychosis. Genetic variation in these skills, under polygenic control,

Genetic limit of functional adaptability
Internationale Zeitschrift f�r Angewandte Physiologie Einschlie�lich Arbeitsphysiologie, 1972A pair of monozygous twins, a trained athlete and his identical untrained counterpart, were tested over a period of 1 1/2 years. Monozygosity was established on the basis of morphological traits and serological criteria. Repeated measurements obtained during basal conditions, submaximal and maximal exercise on a cycle ergometer disclosed that: a) the ...

Adaptive Multicomponent Analysis by Genetic Algorithms
Journal of Chemical Information and Modeling, 2005The applicability of genetic algorithms for solving multicomponent analyses is systematically examined. As a genetic algorithm (GA), the basic proposal of Goldberg is implemented in a straightforward manner to simulate multicomponent analyses in analogy to the well-established UV-vis or IR methods, especially multicomponent regression.
