maintains unique identifiers for the agents. AuctionBot (Wurman et al.) is a flexible,
scalable, and robust auction server which supports software agents.
In our previous work, we have proposed a secure agent fabrication, evolution &
roaming (SAFER) architecture, which aims to construct an open, dynamic, and
evolutionary agent system for e-commerce (Zhu, Guan, & Yang, 2000). It provides
a framework for agents in e-commerce and establishes a rich set of mechanisms to
manage and secure them. We have already elaborated agent fabrication and roaming
in Guan and Yang (1999) and Guan, Zhu, and Ko (2000) respectively. Agent
evolution is an integrated part of the SAFER architecture. We have proposed a
model for agent life cycle and some evolutionary computation methods to evolve
agents (Zhu & Guan, 2001).
Literature in distributed artificial intelligence (DAI) and multi-agent system (MAS)
has addressed agent evolution extensively. Haynes and Wainwright (1995) aim to
evolve programs to control an autonomous agent capable of learning how to survive
in a hostile environment.
