Treap - OI Wiki
Treap(树堆)是一种 弱平衡 的 二叉搜索树。 Treap 的结点除了被维护的 权值 ()之外,还附加了一个随机的 优先级 ()。 其中,权值满足二叉搜索树性质,优先级满足堆性质(小根堆或大根堆)。 其中,二叉搜索树的性质是指: 左子节点的权值()比父节点小。 右子节点的权值()比父节点大。 堆的性质是: 子节点优先级()比父节点大或小(取决于是小根堆还是大根堆)。 不难看出,如果用的是同一个值,那么这两种数据结构在组合后会变成一条链,所以我们再在搜 …

浅析Treap——平衡树 - 洛谷专栏
2018年8月5日 · 首先,我们要知道,Treap=Tree+Heap,Tree指的是二叉排序树,Heap则是指堆 . 1.Tree——二叉排序树. 二叉排序树,是指根的左儿子比根小,右儿子比根大,且左右子树均为二叉排序树的树 通俗来说,就是左子树全部比根小,右子树全部比根大,如图:
史上最强图解Treap总结, 不是浅谈! - CSDN博客
2017年6月1日 · 树堆,在 数据结构 中也称Treap,是指有一个 随机附加域 满足堆的性质的 二叉搜索树,其结构相当于以随机数据插入的二叉搜索树。 其基本操作的期望 时间复杂度 为O (logn)。 相对于其他的平衡二叉搜索树,Treap的特点是实现简单,且能基本实现随机平衡的结构。 Treap 维护堆的性质的方法只用到了左旋和右旋, 编程复杂度比Splay小一点, 并且在两者可完成的操作速度有明显优势. 每一个节点需要保存至少四个信息,当前节点的数值 ( val ), 优先级 ( key …
数据结构之平衡树(Treap) - CSDN博客
平衡树是 二叉搜索树 和 堆 合并构成的新 数据结构,所以它的名字取了Tree和Heap各一半,叫做Treap。 堆和树的性质是冲突的, 二叉搜索树 满足左子树<根节点<右子树,而堆是满足根节点小于等于 (或大于等于)左右儿子。 因此在Treap的数据结构中,并不是以单一的键值作为节点的数据域。 Treap每个节点的数据域包含2个值,key和weight。 key值,和原来的二叉搜索树一样,满足左子树<根节点<右子树。 weight值,随机产生。 在Treap中weight值满足堆的性质,根节点 …

PATtree索引方法详解-CSDN博客
PAT tree是由所有可能的无限长字串所构成的一棵树。在PAT tree中通过逐个鉴别半无限长字串的二进制位来判断树中的分支,如果二进制位是0则产生左分支,是1则产生右分支,因此PAT tree是一棵二叉树,树的结点分为外部结点和内部结点。
