Agents blend many of the traditional properties of AI programs - knowledge-level reasoning , flexibility , proactiveness , goal-directedness , and so forth - with insights gained from distributed software engineering , machine learning , negotiation and teamwork theory , and the social sciences .

Agent programs are designed to autonomously collaborate with each other in order to satisfy both their internal goals and the shared external demands generated by virtue of their participation in agent societies .
