4.调优搜索调优过程的一些特点:首先,调优操作是一个渐进过程,其中每一步追求的是有所改进且不扰乱生产,因此,感兴趣的不仅是最佳点,而更重要的是通往最佳点的路径,路径上那许多点会提供更多的信息,可以作比较和选择用。这种路径将称之为调优路径。事实上,“最佳”往往难以达到,不如放松一点要求,把好到极点的“最佳”改为令人满意的“优惠”。其次,调优对操作条件的改变应是微小的,因此求解总是在一些现行操作点附近进行的,即在给定的初始点的邻域内寻求优惠解,而现行操作点附近会有一个范围允许操作条件变化,有
4. Tuning Some features of the search tuning process: First, tuning is a gradual process in which each step is pursued to improve and not disrupt production, so it is not only the best point, but the more important Is the path to the best point, and many points in the path provide more information for comparison and choice. This path will be called the tuning path. In fact, “best” is often difficult to achieve. Rather, it is better to relax and change the “best of the best” to the satisfactory “concession”. Second, the tuning changes to the operating conditions should be minimal, so the solution is always performed near some current operating point, ie, seeking a discount solution in the neighborhood of a given initial point, and there is a range near the current operating point Allowed to change the operating conditions, there
