Agent-Based Models of Strategies for the Emergence and Evolution of Grammatical Agreement

Figure 2

Combinatorial complexity of interpretation.

Left: The number of possible hypotheses grows exponentially with the number of words as predicted by equation (1). Right: Percentage of remaining hypotheses and remaining semantic ambiguity after the application of selection restrictions (left) or the consultation of the situation model (right), for 50 game series with 10 agents and 5000 games in total (1000 per agent). Average values are shown with standard deviations. Both sources of information reduce the set of possible hypotheses in the search space but significant semantic ambiguity remains.
