Abstract

Some characteristics of the tuning search and tuning process: First, the tuning operation is a gradual process, in which each step pursues improvement without disturbing production. Therefore, what is interesting is not only the best point, and more importantly, the path leading to the best point. The many points on the path will provide more information and can be used for comparison and selection. This path will be called the tuning path. In fact, the "best" is often difficult to achieve. It is better to relax your requirements and change the extremely good "best" into a satisfactory "discount". Secondly, the changes in operating conditions caused by tuning should be minimal, so the solution is always performed near some current operating points, that is, a preferential solution is sought within the neighborhood of a given initial point, and there will be a range near the current operating points. Changes in operating conditions are allowed,
