What Isn't Complexity?
Christopher R. Stephens
The question What is Complexity? has occupied a great deal of time and paper over the last 20 or so years. There are a myriad different perspectives and definitions but still no co…
Self-Organization Promotes the Evolution of Cooperation with Cultural Propagation
Luis Enrique Cortés-Berrueco, Carlos Gershenson, Christopher R. Stephens
In this paper three computational models for the study of the evolution of cooperation under cultural propagation are studied: Kin Selection, Direct Reciprocity and Indirect Recipr…
Is modularity the reason why recombination is so ubiquitous?
Manuel Beltrán del Río, Christopher R. Stephens, David A. Rosenblueth
Homologous recombination is an important operator in the evolution of biological organisms. However, there is still no clear, generally accepted understanding of why it exists and…
Cellular automaton supercolliders
Genaro J. Martinez, Andrew Adamatzky, Christopher R. Stephens +1
Gliders in one-dimensional cellular automata are compact groups of non-quiescent and non-ether patterns (ether represents a periodic background) translating along automaton lattice…
Approximating Mexican highways with slime mould
Andrew Adamatzky, Genaro J. Martinez, Sergio V. Chapa-Vergara +2
Plasmodium of Physarum polycephalum is a single cell visible by unaided eye. During its foraging behavior the cell spans spatially distributed sources of nutrients with a protoplas…
Two-Loop Crossover Scaling Functions of the O(N) Model
Denjoe O'Connor, J. A. Santiago, C. R. Stephens +1
Using Environmentally Friendly Renormalization, we present an analytic calculation of the series for the renormalization constants that describe the equation of state for the $O(N)…
