Agent-Based Models of Strategies for the Emergence and Evolution of Grammatical Agreement
i) Average performance values for 50 game series for a total of 50,000 games (average of 10,000 per agent). The probability that the speaker phonologically reduces a marker is per game. We see that the length of the markers progressively diminishes, thus reducing articulatory effort, but variation does not increase, implying that the system is stable. The marker inventory size remains constant as well. ii) Trace of the changes to a marker in a single experiment. The marker -uinbui erodes progressively to -u. A truncated variant is typically present for a while in the population until a phase transition happens and it becomes dominant.
