【Abstract】 The contract net model is used for distributed problem solving and task allocation in application systems based on agent. To overcome several defects in solving real problem, a concept of task acquaintance is introduced,then a extention of the contract net model is presented,which chooses strategy dynamically during negotiation. The strategy of negation based on task acquaintance can reduce cost of communication, and can compute effectively during negotiation.更多还原
