... If you start from any node and move upward, you will eventually reach the root. Every node except the root has one parent. The root has no parent. Complete binary trees require the nodes to fill in each level from left-to-right before starting the next level. Full binary trees ...

Dynamic Optimality—Almost ∗ Erik D. Demaine Dion Harmon
... The auxiliary tree data structure is an augmented BST that stores a subpath of a root-to-leaf path in P (in our case, a preferred path), but ordered by key value. With each node we also store its fixed depth in P . Thus, the depths of the nodes in an auxiliary tree form a subinterval of [0, lg(n + 1 ...

Introduction to Data Structures Using C
... One important relationship in the binary tree is the parent-child relationship. Parent nodes have at least one edge to the node lower in the tree. This lower node is called the child node. Nodes can have more than one child, but the children can only have a single parent. Notice that the root node ...

... Typically the child nodes are called left and right. Definitions for rooted trees A directed edge refers to the link from the parent to the child (the arrows in the picture of the tree). The root node of a tree is the node with no parents. There is at most one root node in a rooted tree. A leaf is a ...

Concurrent Search Tree by Lazy Splaying

Following splay tree BST techniques [15] in lazy splaying we perform one tree rotation (kind of re-balancing) at the node containing the item we operate on, moving subtrees with more frequently accessed nodes one level up on the a ...

Hierarchical Data Structures
... Explain in detail how to use a bounding box hierarchy to identify the intersection between a ray and the closest object in the environment. Your algorithm should, of course, be more efficient (in the general case) than the brute force process of checking the ray for intersection with all objects. ...

Quadtree
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
