Spatially Distributed Naming Games [PDF]

open access: yesAdvances in Complex Systems, 1998
The paper investigates the dynamical properties of spatially distributed naming games. Naming games are interactions between two agents, a speaker and a hearer, in which the speaker identifies an object using a name. Adaptive naming games imply that speaker and hearer update their lexicons to become better in future games.
