Vertices (nodes) represent BCR IGH sequences, and the weight of edges connecting vertices represents the distance between sequences in terms of mutation, insertion, and deletion operations. All observed sequences are reachable from the root (the inferred naive/unmutated BCR IGH sequence). Minimum ...

However,B-tree can store many keys in a single node and can have multiple child nodes.This decreases the height significantly allowing faster disk accesses. B树应用 数据库和文件系统 存储数据块(辅助存储介质) 多级索引 B Tree Applications
The balancing of the tree is not perfect but it is good enough to allow it to guarantee searching in O(log n) time, where n is the total number of elements in the tree. The insertion and deletion operations, along with the tree rearrangement and recoloring, are also performed in O(log...
