Question: There are n people. The weight of the I-th person is wi. The maximum carrying capacity of each ship is C, and only two people can be taken at most. Use the least ship to load the owner. Analysis: greedy! Who should I sit? If everyone cannot get on a ship with him, the only solution is that everyone can get on a ship! Otherwise, he should choose the heaviest j among the people who can take the boat with him. This method is greedy! Because: it only makes the "present" Waste the least

Based on the preceding algorithm, I will explain the most basic sorting algorithm, that is, selecting the sorting algorithm. I think this is the simplest sorting method, and the idea is also well understood, in order to extend the foundation, I will explain the idea of a Bubble Sorting Algorithm. Of course, this is just the simplest basic implementation method. I hope it can be used as the best reference for beginners, let me first talk about the basic principle of implementing the bubble algori

rendered in fully per-pixel lit mode. Then, the up to 4 point lights is calculated Per-vertex. The other lights was computed as spherical harmonics (SH), which is much faster but was only a approximation. Whether a light would be per-pixel light or not are dependent on this:In forward rendering, the lightest light sources that affect an object use pixel-by-light mode. Next, up to 4 point lights are calculated as vertex-by-pixel rendering. Other light
