Skip Ring/Circular Skip List: Circular Linked List Based
... but we need a special representation for the empty list, such as a last node variable which points to some node in the list or is null if it's empty. This representation significantly simplifies adding and removing nodes with a nonempty list, but empty lists are then a special case. Circular linked ...

We assume an adversarial user does not have access to the levels of nodes; otherwise, he could create situations with worst-case running times by deleting all nodes that were not level 1. The probabilities of poor running times for successive operations on the same data structure ar ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
