Social interactions involving coordination between individuals are subject to an "evolutionary trap." Once a suboptimal strategy has evolved, mutants playing alternative counterselected because they fail coordinate with the majority. This creates detrimental situation from which evolution cannot escape, preventing of efficient collective behaviors. Here, we study this problem using evolutionary robotics simulations. We first confirm existence trap in simple setting. then, however, reveal...

Mutualistic cooperation often requires multiple individuals to behave in a coordinated fashion. Hence, while the evolutionary stability of mutualistic poses no particular theoretical difficulty, its emergence faces chicken and egg problem: an individual cannot benefit from cooperating unless other already do so. Here, we use robotic simulations study consequences this problem for evolution cooperation. In contrast with standard game-theoretic results, find that transition solitary...

In this paper, we investigate the benefits and drawbacks of different approaches for solving a cooperative foraging task with two robots. We compare classical clonal approach an additional which favors evolution heterogeneous behaviors according to defining criteria: evolvability solution efficiency coordination evolved. Our results reveal tradeoff between efficiency: evolves cooperation higher probability than non-clonal approach, but evolved systematically show better fitness scores. then...

Displaced communication, whereby individuals communicate regarding a subject that is not immediately present (spatially or temporally), one of the key features human language. It also occurs in few animal species, most notably honeybee, where waggle dance used to location and quality patch flowers. However, it difficult study how emerged given paucity species displaying this capacity fact often via complex multimodal signals. To address issue, we developed novel paradigm which conducted...

In this article, we are intested in the evolution of specialisation among a single population heterogeneous robotic agents cooperative foraging task.In particular, want to compare (1) emergence and (2) fixation genotypic polymorphism under two different selection methods: elitist fitness-proportionate.We show that, while specialists is easy an selection, method cannot maintain behaviours throughout whole simulation.In comparison fitness-proportionate algorithm proves be inefficient evolving...
