       An information-theoretic model for communication
        

We examine the cost-minimization problem posed by Ferrer i Cancho and 
Solé in their information-theory based communication model (R. Ferrer 
i Cancho and R. V. Solé, PNAS 100, 788 (2003)), proposed in efforts 
to explain Zipf's Law (power law frequency-rank relation for words in 
written texts). We obtain the exact minimum-cost solutions as 
obtained previously via other methods. The model exhibits three 
qualitatively different behaviors according to the relative 
importance of speaker and listener costs. At the phase transition, 
the minimum-cost solutions do not correspond to a power law except 
for a vanishingly small subset.
