Higher lines indicate schedules which have been more profitable to date.
With neural net learning, mixed bundling performs extremely well. It has the highest profits of any schedule for about 100 periods, and thereafter is close to the leader, two-part tariff. Contrary to our expectations, the one-parameter schedules didn't perform particularly well, even during the learning phase. Note that the rate of convergence is not a good measure for comparing price schedules, since it does not reflect the quality of the final solution. For example, nonlinear pricing converges quickly to a local optimum, and thereafter obtains very poor profits.
