A simple model of tag-mediated partner selection for agents playing the IPD is described. The agents strategies are represented as (i,q,q) triples as in [Nowak and May, 1992]. The tags are represented as arbitrary real numbers in [0,1], and tag selection is biased toward agents with similar...

While complex adaptive systems (CAS) theories focus primarily on phenomena such as systemic robustness against perturbation, self-organization, and on the emergence, transformation, and dissolution of organizational entities or action patterns, the metaphorical resonance of CAS work is not...

Communication plays a vital role in the organization and operation of biological, computational, economic, and social systems. Agents often base their behavior on the signals they receive from others and also recognize the importance of the signals they send. Here we develop a framework for...

The evolution of cooperation in the repeated prisoner's dilemma depends on the conditions under which the game is … affected by the localisations of both interaction and learning. While the localisation of learning promotes mutual cooperation …, the localisation of interaction has an ambiguous effect on it. Moreover, the localisation of learning seems to promote …

Environmental and biotic factors regulate species abundance and the composition of ecological communities. However, it is difficult to demonstrate principles of community assembly in nature due to observational limitations and historical effects. Numerical simulation can be used to evaluate...

Fitness distance correlation (FDC) has been offered as a summary statistic with apparent success in predicting the performance of genetic algorithms for global optimization. Here, a counterexample to Hamming-distance based FDC is examined for what it reveals about how GAs work. The...

Current techniques of DNA analysis enable the scoring of hundreds of electrophoretic bands using a small amount of DNA from an individual. The sample size in pilot experiments is typically orders of magnitude smaller then the number of bands contained in a molecular profile. Nevertheless, it is...
