Catastrophic Phase Transitions and Early Warnings in a Spatial Ecological Model
Ariel Fernandez, Hugo Fort
Gradual changes in exploitation, nutrient loading, etc. produce shifts between alternative stable states (ASS) in ecosystems which, quite often, are not smooth but abrupt or catast…
Random mobility and spatial structure often enhance cooperation
Estrella A. Sicardi, Hugo Fort, Mendeli H. Vainstein +1
The effects of an unconditional move rule in the spatial Prisoner's Dilemma, Snowdrift and Stag Hunt games are studied. Spatial structure by itself is known to modify the outcome o…
On Evolutionary Spatial Heterogeneous Games
H. Fort
How coperation between self-interested individuals evolve is a crucial problem, both in biology and in social sciences, that is far from being well understood. Evolutionary game th…
Evolutionary Markovian Strategies in 2 x 2 Spatial Games
Hugo Fort, Estrella Sicardi
Evolutionary spatial 2 x 2 games between heterogeneous agents are analyzed using different variants of cellular automata (CA). Agents play repeatedly against their nearest neighbor…
Prisoner's Dilemma cellular automata revisited: evolution of cooperation under environmental pressure
Julia Alonso, Ariel Fernandez, Hugo Fort
We propose an extension of the evolutionary Prisoner's Dilemma cellular automata, introduced by Nowak and May \cite{nm92}, in which the pressure of the environment is taken into ac…
Spatial patterns and scale freedom in a Prisoner's Dilemma cellular automata with Pavlovian strategies
H. Fort, S. Viola
A cellular automaton in which cells represent agents playing the Prisoner's Dilemma (PD) game following the simple "win-stay, loose-shift" strategy is studied. Individuals with bin…
