overbite

We analyze agent cooperation methods now commonly in use , and , on the basis of ecology and experiences , we propose a competitive price auction contract network protocol . while using the same network traffic volume as the simple auction , our strategy of second overbid competitive price auction can achieve the same effect as the traditional auction . further , we improve traditional contract network protocol , introduce constraints into message transmit , and use fell back punishment and credit when an agent cannot complete the intended task , consequently the traffic volume and the complexity of systems are considerably reduced 本文分析了現在通常采用的agent協同方法,提出基于生態學和經驗的競價拍賣合同網協議,采用的選擇次高價競價拍賣策略能在與簡單拍賣相同的通信量上達到類似于傳統競價拍賣的效果,對傳統的合同網協議進行改進,在消息傳播中加入約束機制和對agent不能完成任務時不采取轉變角色重新招標而采用違約懲罰和信用機制,減少了系統的通信量和系統的復雜度,最后在此基礎上實現一個基于fipa標準的多agent電子商務原型系統。
