Some strategies for the simulation of vocabulary agreement in multi-agent communities

In this paper, we present several experiments of belief propagation in mult i-agent communities. Each agent in the simulation has an initial random voc abulary (4 words) corresponding to each possible movement (north, south, ea st and west). Agents move and communicate the associated word to the surrou nding agents, which can be convinced by the 'speaking agent', and change th eir corresponding word by 'imitation'. Vocabulary uniformity is achieved, b ut strong interactions and competition can occur between dominant words. Se veral moving and trusting strategies as well as agent roles are analyzed.
