Heaps

Heaps. Chapter 10 has several programming projects, including a project that uses heaps . This presentation shows you what a heap is, and demonstrates two of the important heap algorithms. This chapter also takes a look at B-trees. Data Structures and Other Objects Using Java. Heaps.

AVL Trees

AVL Trees. When bad trees happen to good programmers. Good tree. Bad tree. Bad tree. Left and right subtrees have the same height!. For every node in the tree, the left and right subtrees of that node have the same height. Too rigid. AVL Trees. (Adelson-Velskii and Landis)

AVL Trees

AVL Trees. Balanced Trees. AVL Tree Property. A Binary search tree is an AVL tree if : the height of the left subtree and the height of the right subtree differ at most by one, and the left and right subtrees are also AVL trees

B-Trees

B-Trees. Motivation for B-Trees. Index structures for large datasets cannot be stored in main memory Storing it on disk requires different approach to efficiency Assuming that a disk spins at 3600 RPM, one revolution occurs in 1/60 of a second, or 16.7ms

Traversals

Traversals. A systematic method to visit all nodes in a tree Binary tree traversals: Pre-order: root, left, right In-order: left, root, right Post-order: left, right, root General graph traversals (searches) Depth-first search Breadth-first search. Inorder(tree t). if t = nil

AVL Trees

AVL Trees. Motivation: we want to guarantee O(log n) running time on the find/insert/remove operations. Idea: keep the tree balanced after each operation. Solution: AVL (Adelson-Velskii and Landis) trees.

Chapter 4: Trees

Mark Allen Weiss: Data Structures and Algorithm Analysis in Java. Chapter 4: Trees. AVL Trees. Lydia Sinapova, Simpson College. AVL Trees. Keep the tree balanced Use node rotation Balanced condition: The left and the right subtrees of each node should differ by at most one level.
