我理解的数据结构(五)—— 二分搜索树(Binary Search Tree) 一、二叉树 和链表一样,动态数据结构 具有唯一根节点 每个节点最多有两个子节点 每个节点最多有一个父节点 具有天然的递归结构 每个节点的左子树也是二叉树 每个节点的右子树也是二叉树 一个节点或者空也是二叉树 二、二分搜索树 是二叉树 每个节点...
这棵二叉搜索树每个节点的左侧是这个节点具有的左子节点的个数, 也就是书上对于二叉索引树的定义, 这个定义从二叉搜索树衍生 如果要在这颗树上查找索引为 3 的节点, 那么对应的元素应该是 23; 如果要在这棵树上查找索引为 4 的节点, 那么对应的元素应该是 34 我在网上查找过一些关于二叉索引树的资料, 网上...

Continuous search¶Let f:R→R be a real-valued function that is continuous on a segment [L,R] .Without loss of generality assume that f(L)≤f(R) . From intermediate value theorem it follows that for any y∈[f(L),f(R)] there is ...
The known patterns are exemplified as Optimal Binary Search Trees (OBST) based on their mean values. Since searching is efficient in OBST, this technique is efficient for pattern matching in time series data. TheACO is used for comparing a particular pattern and the current window of the time...
