WebThe Cost of a Splay We need to prove that splaying is amortized efficient. Historically, it has proven hard to analyze splay trees for several reasons: Each lookup can significantly reshape the tree.

Web1 Feb 2024 · Splay正是一种平衡树，它的基本思想是对于“访问频繁”的节点，就把这些节点移动到靠近根的位置，以此提高整体操作的效率。我们可以认为每次访问的目标节点就是访问频繁的节点，每次操作后，就对二叉查找树进行重构，把被访问的节点搬到离根近的地方。于是，每次都把被访问节点搬到根节点的Splay应运而生。原理详解通过上面的简介，可 … WebThe Cost of a Splay We need to prove that splaying is amortized efficient.

WebA splay tree is an efficient implementation of a balanced binary search tree that takes advantage of locality in the keys used in incoming lookup requests. For many applications, there is excellent key locality. A good example is a network router. WebSplay covers almost everything Fenwick Tree and Segment Tree can do so I would argue it is a Swizz knife in sequence manipulation. But again, the main argument against Splay is not what it cannot do, but the fact that it is slower than simple data structures like Fenwick Tree by a constant factor, just like how a Swizz knife does not excel in simpler tasks :)

WebThis paper proves the sequential access theorem, which implies as a special case that accessing the items in a splay tree in sequential order takes linear time, i.e.O(1) time per access.
