Games and physics simulations need to detect which objects are touching or overlapping. With nnn objects, checking every pair is O(n2)O(n^2)O(n2) comparisons, which gets expensive fast. A hundred objects means roughly 5,000 pair checks. A thousand means nearly 500,000.
If we could simply rewind time and watch the code execute exactly as it did for those failed requests, life would be a lot easier.。WPS下载最新地址是该领域的重要参考
