In this paper we present a model partially based on the idea of language games, so that a group of artificial agents are able to produce and share a symbolic language with syntactic structure. Grammatical structure is induced by grammatical evolution of stochastic regular grammars with learning capabilities, while language development is refined by means of language games where the agents apply on-line probabilistic reinforcement learning. Within this framework, the model adapts the concepts of competence and performance in language, as they have been proposed in some linguistic theories. The first experiments in this article have been organized around the linguistic description of visual scenes with the possibility of changing the referential situations. A second and more complicated experimental setting is also analyzed, where linguistic descriptions are enforced to keep word order constraints.eng© Elsevier, 2016Atribución-NoComercial-SinDerivadas 3.0 Españastochastic grammarsgrammatical evolutionlanguage gamesmulti-agents systemsresearch articleInformáticahttps://doi.org/10.1016/j.ins.2016.08.088open access7994INFORMATION SCIENCES373AR/0000029105
