A bidding strategy between agents based on double auction

In some systems, running after a period of time, agents form cooperation partnership. However, there are two problems in the bidding strategy of double auction between cooperative agents. Firstly, the auctioneer or bidder can´t make an effective response to the pricing program while the opposite changes itself strategy. Secondly, because of incomplete information, the bargain efficiency is low in equilibrium. Aimed at these problems, a conception of favor degree is presented from the views of both auctioneer and bidder, and it is used to simulate the stimulation of nerve cells. This paper brings forward a novel bidding strategy of double auction based on the favor degree, which makes the two agents call for the long-term interests rather than immediate interests. So this strategy enlarges the trading range and improves the trading efficiency. Finally, the validity of the model is proved by a case.
