For well-distributed points, nearest neighbor search is often near O(logn)O(\log n)O(logn) in practice. In the worst case (all points clustered tightly or along a line), it can degrade to O(n)O(n)O(n), but this is uncommon with typical spatial data.
For SAT problems with 10 variables and 200 clauses, sometimes outputted UNSAT because it couldn't find any satisfying assignment, and it would take a lot more time to find one, which is logically sound. I don't consider this as bad reasoning as it is about performance. So I tried it with only 100 clauses and it successfully found valid assignments.。搜狗输入法下载对此有专业解读

啪，的士车门打开，女强人前腿一抬，腰身一欠，贵宾驾到。水车屋，她来过无数次的日本料理店，当年客人带妈咪和小姐吃宵夜的指定场所。十几年前来水车屋是要排队的，大批酒意未消的人马聚集在店门口，然后径直走向三楼铁板烧——店里消费最高的区域。吃宵夜，那是很有面子的事情，还意味着一笔不菲的“买钟”钱（客人把女公关带出夜总会所支付的费用）。

集市热热闹闹，总也走不完，像春节庙会。小时候见过扭秧歌、跑旱船、踩高跷，也看放烟花，像看唱戏一样。晚上冻得嘶嘶哈哈，杵在那儿。玩火药的蔡国强，我老感觉见过——冬拍了太多名人，照片多是我挑，挑来挑去，成了老熟人，好像街坊邻居。
