We use symbolic regression (implemented by a genetic program) to analyze the role of agent expectation formation in games. In the model, agents attempt to infer the strategies of opponents through regression and then best respond using this information. Though agents use deterministic...

Emergence is a universal phenomenon that can be defined mathematically in a very general way. This is useful for the study of scientifically legitimate explanations of complex systems, here defined as hyperstructures. A requirement is that the observation mechanisms are considered within the...

We consider the general problem of constructing a physical map of genome by welding islands of overlapping clones. Both distribution of clone length and nonuniform probability of overlap detection are taken into account, the latter restricted to the Markov case in which only the location of the...

n Gene Perturbations in Fewer than n2 Easy Steps <p> [gzipped postscript] [postscript] [pdf] <p> Andreas Wagner <p>I present an algorithm to reconstruct direct regulatory interactions in gene networks from the effects of genetic perturbations on gene activity. Genomic technology has made feasible...</p></p></p>

We propose an explanation of cooperation among unrelated members of a social group, in which providing group benefits evolves because it constitutes an honest signal of the member's quality as a mate, coalition partner or competitor, and therefore results in advantageous alliances for those...

We show that the way in which the Shannon entropy of sequences produced by an information source converges to the source's entropy rate can be used to monitor how an intelligent agent builds and effectively uses a predictive model of its environment. We introduce natural measures of the...

Many properties of organisms show great robustness against mutations. Whether this robustness is an evolved property or intrinsic to genetic systems is by and large unknown. An evolutionary origin of robustness would require a rethinking of key concepts in the field of molecular evolution, such...

The population dynamics of macromolecules that reproduce by means of template-directed ligation of two fragments are shown to be represented by a replicator equation with a special non-linear response function. This result is obtained through detailed consideration of the mechanism of ligation...
