TODO: does NOT work well for the moment. 1. need learn from other specialists as well 2. need more reasonable esitmated utility of a fee in terms of trader popularity 3. IndivProfit list never gets full as with TraderNum list - check it out !

An adaptive charging policy that estimates the utilities of charges once imposed and then calculate a charge that maximizes the expected utility. ReverseDiscountSlidingLearner is currently supposed to be used to estimate the trader popularity with a certain fee.

Parameters
