A Java implementation ofskip list. 跳表的Java语言实现。 Introduction Skip lists are data structures that use probabilistic balancing rather than strictly enforced balancing. As a result, the algorithms for insertion and deletion in skip lists are much simpler and significantly faster than equivalent alg...

and proceeds horizontally until the current element is greater than or equal to the target. If the current element is equal to the target, it has been found. If the current element is greater than the target, or the search reaches the end of the linked list, the procedure is repeated aft...

跳表(skip list) 数组和链表对比: 数组支持随机访问,根据下标随机访问的时间复杂度是 O(1) 数组的插入和删除操作效率不高,平均情况下的时间复杂度是 O(logN) 链表随机访问性能没有数组好,平均情况下的时间复杂度是 O(logN) 链表插入和删除操作只需要改变相邻节点的指针,时间复杂度是 O(1) ...

We show that the splay-list provides order-optimal amortized complexity bounds for a subset of operations, while being amenable to efficient concurrent implementation. Experiments show that the splay-list can leverage distribution-adaptivity for performance, and can outperform the only previously-known ...
