1972 年,Bayer 和 McCreight 两位大佬发表了一篇数据库领域举足轻重的论文《Organization and maintenance of large ordered indexes》,并在论文中提出了一个名为“B-trees”的数据结构,中文一般翻译成 B 树。 “B-tree”中的“-”只是用来分割 “B” 和“tree”的,如果将其翻译成“B-树”其实不太合理,没人...

Forests aren't simply collections of trees, they're complex systems with hubs and networks that overlap and connect trees and allow them to communicate, and they provide avenues for feedbacks and adaptation, and this makes the forest resilient. 森林不...
