The nodes carrying keys and/or data are frequently called "internal nodes", but to make this very specific they are also … See more In computer science, a red–black tree is a specialised binary search tree data structure noted for fast storage and retrieval of ordered information, and a guarantee that operations will complete within a known time. … See more In 1972, Rudolf Bayer invented a data structure that was a special order-4 case of a B-tree. These trees maintained all paths from root to leaf with the same number of nodes, creating perfectly balanced trees. However, they were not binary search trees. … See more A red–black tree is similar in structure to a B-tree of order 4, where each node can contain between 1 and 3 values and (accordingly) … See more The read-only operations, such as search or tree traversal, on a red–black tree require no modification from those used for binary search trees, because every red–black tree is a special case of a simple binary search tree. However, the immediate result of … See more In addition to the requirements imposed on a binary search tree the following must be satisfied by a red–black tree: 1. Every node is either red or black. 2. All NIL nodes (figure 1) are considered black. 3. A red node does not have a red child. See more Red–black trees offer worst-case guarantees for insertion time, deletion time, and search time.
