....that was outlined above and first derive what would be the optimal lexicon , i.e. the lexicon that leads to the highest communicative success in the population. To do so, we need a measure for communicative success. Such a measure is presented next; a similar formalism was used in (Hurford, 1989; Nowak Krakauer, 1999; De Jong, 2000, and other papers) The next step then is to evaluate numerically if the collective dynamics can lead to such an optimal situation. We denote with S i ( f jm) the probability that an agent i uses form f to express meaning m. Similarily, R i (mj f ) is the probability that ....

....papers reports on the model presented by Hashimoto Ikegami (1996) that studies evolution of rewriting grammars. Batali (1994) studied a system of agents with simple recurrent neural networks, in which evolution leads to innate biases that enable agents to efficiently learn recursive languages. Nowak Krakauer (1999) formulated a mathematical model, that shows that compositionality can help overcome an error limit on 2 successful communication, and thus should be expected to be selectively advantageous. 1.3 genetic transmission Proponents of the genetic transmission scenario, view evolution of language as ....

....expressiveness with the limitations in human learning and memory. This aspect is, in the traditional view, what makes syntax selectively advantageous, and caused the transition from an extensive non syntactical protolanguage to a more efficient, syntactical language system (Pinker Bloom, 1990; Nowak Krakauer, 1999). We study this transition in a computational model of an evolving population of communicating agents. The main advantages of computational and mathematical models such as (Hurford, 1989; Steels, 1997; Hashimoto Ikegami, 1996; Nowak Krakauer, 1999) are that they are relatively precise and ....

....parts of language are innate, some are learned view. Computational modeling Recent work that studied such interactions in computational models has produced a wealth of new hypotheses and insights (Hurford, 1989; Hashimoto Ikegami, 1996; Batali, 1997; Steels, 1997; De Boer, 1999; Kirby, 2000; Nowak Krakauer, 1999; Hurford, 2000) Such models are relatively precise implementations of the underlying set of assumptions, and allow one to evaluate the internal coherence of such a set. Moreover, they are productive, in the sense that they often show unexpected behaviors that help to generate new hypotheses and ....
....(the in nite I language ) is transmitted culturally (via a nite E language ) from one agent to another. This transmission bottleneck works as a lter, in which syntactic elements of language typically out compete non syntactic elements, because the former are inherently used more often. Nowak Krakauer (1999) studied a game theoretic model of language evolution and identify a di erent mechanism that can account for the emergence of syntax. Using the matrix representations of Hurford (1989) they infer a linguistic error limit . Given that an individual makes mistakes in distinguishing sounds with a ....

Individuals who communicate successfully leave more ospring (thus the factors f in equations (1) and (2) who in turn learn their language. This puts the problem of grammar acquisition in an evolutionary context (Nowak Krakauer 1999; Nowak et al. 1999, 2000) Finally, the quantity in equations (1) and (2) is the average tness of the population.
