NLF said that without considering specific problems, none of the algorithms were better than the other, and not even guesswork. Without a specific application, the universally applicable "optimal classifier" learning algorithm must make a "hypothesis" related to the problem domain, and the classifier must adapt to the problem field.
However, the premise of the NFL theorem is that all problems appear equal opportunities, or that all problems are equal
equivalent. No free lunch indicates that the average performance obtained by different algorithms for different problems is higher than that obtained by the same algorithm for all problems. Igel, Toussaint, and English have determined that there are no general conditions for free lunch. Although this is theoretically possible, the actual situation is not 100% in line with the theory. Droste, Jansen, and Wegener prove a theorem-in fact, "almost no free lunch ".
Let's make the problem specific. S

, the point in the figure is a training sample, the curve through these points are theoretically satisfied with the "condition" of the hypothetical model, but we intuitively prefer the smooth blue dashed line instead of red. If the algorithm is an inductive preference, we think that the smoothed Blue line is the "right" model that we recognize.

Oracle logs blocks with free space for insert or update. Free space comes in two ways: 1. All blocks over HWM in the segment have been assigned to segments, but have not yet been used. 2. All the blocks under HWM in the paragraph that are linked into the free list can be
