摘要
We propose a model that explains the reliable 湧現 of 冪次定律s (e.g., Zipf's law) during the development of different human 語言s. The model incorporates the principle of least effort in communications, minimizing a combination of the 資訊-theoretic communication inefficiency and direct signal cost. We prove a general relationship, for all optimal 語言s, between the signal cost distribution and the resulting distribution of signals. Zipf's law then emerges for logarithmic signal cost distributions, which is the cost distribution expected for words constructed from letters or phonemes.
