Arms Races and Car Races

Evolutionary car racing (ECR) is extended to the case of two cars racing on the same track. A sensor representation is devised, and various methods of evolving car controllers for competitive racing are explored. ECR can be combined with co-evolution in a wide variety of ways, and one aspect which is explored here is the relative-absolute fitness continuum. Systematical behavioural differences ...

Human races

Carl was not a geneticist by training or at heart, and although cognizant of horizontal gene transfer, saw it as a creative force at the beginning of cellular evolution (the ‘progenote’ stage), not as a challenge to defining the ‘true’ relationships between living things now. Most of the phylogenetic community still holds Carl’s belief as foundational. Nor was he, as Mayr complained, a card-car...

Evolution: Sexual Arms Races

The reproductive interests of males and females usually differ, resulting in sexual conflict. Recent studies in which experimental selection trials were carried out under conditions of either 'high' or 'low' sexual conflict show that conflict can promote speciation and reduce female reproductive success.

Abstract Interpretation Against Races

Interpretation against Races Roberto Barbuti Stefano Cataudella Luca Tesei Dipartimento di Informatica – Università di Pisa Via F. Buonarroti, 2 56127 Pisa Italy email: Abstract. In this paper we investigate the use of abstract interpretation techniques for statically preventing race conditions. To this purpose we enrich the concurrent object calculus conc by annotating terms with the set of “l...
