This document discusses randomized data structures and algorithms. It begins by motivating randomized data structures as a way to transform average case runtimes into expected runtimes that are not dependent on specific inputs. It then provides examples of randomized data structures like treaps and randomized skip lists that provide efficient operations like insertion, deletion, and search in expected logarithmic time. It also discusses how randomization can be applied in algorithms like primality testing.

The document discusses minimum spanning trees and two algorithms for finding them: Prim's algorithm and Kruskal's algorithm. Prim's algorithm works by growing a spanning tree from an initial node, always adding the lowest cost edge that connects to a node not yet in the tree. Kruskal's algorithm sorts the edges by cost and builds up a spanning tree by adding edges in order as long as they do not form cycles. Both algorithms find optimal minimum spanning trees for weighted, undirected graphs.
This document discusses binary search trees (BSTs) and their use for dynamic sets. It covers BST operations like search, insert, find minimum/maximum, and successor/predecessor. It also discusses how BSTs can be used to sort in O(n log n) time by inserting elements in order and performing an inorder traversal, similar to quicksort. Maintaining a height of O(log n) for BSTs is discussed as an area for future improvement.

This document describes operations on a B-tree including insertion, deletion, splitting and merging of nodes. It shows a B-tree initially containing 26 items in a balanced structure with all leaves at the same level. Keys are added to the leaf nodes, causing splits that promote keys up the tree and rebalance the structure. Deletion is demonstrated by borrowing or merging with neighboring nodes, or demoting and promoting keys when underflow occurs.
This document discusses divide-and-conquer algorithms and their time complexities. It begins with examples of finding the maximum of a set and binary search. It then presents the general steps of a divide-and-conquer algorithm and analyzes time complexity. Several algorithms are discussed including quicksort, merge sort, 2D maxima finding, closest pair problem, convex hull problem, and matrix multiplication. Strategies like divide, conquer, and merge are used to solve problems recursively in fewer comparisons than brute force methods. Many algorithms have a time complexity of O(n log n).

Skip lists are a data structure for implementing dictionaries. They consist of multiple sorted lists, with the top list containing all elements and lower lists being subsequences. Searching works by dropping down lists until finding the target element or determining it is absent. Insertion and deletion use a randomized algorithm adding/removing elements from the appropriate lists. Analysis shows the expected space is O(n) and search, insertion and deletion times are O(log n), with these bounds also holding with high probability. Skip lists provide fast, simple dictionary implementation in practice.

1) Tree data structures involve nodes that can have zero or more child nodes and at most one parent node. Binary trees restrict nodes to having zero, one, or two children.
2) Binary search trees have the property that all left descendants of a node are less than the node's value and all right descendants are greater. This property allows efficient searches, inserts, and deletes that take O(log n) time on average.
3) Trees can become unbalanced over many insertions and deletions, affecting performance of operations. Various self-balancing binary search tree data structures use tree rotations to maintain balance.

Kruskal's algorithm is used to find the minimum spanning tree of a connected, undirected graph. It works by sorting the edges by weight and building up the minimum spanning tree by adding edges one by one if they do not form cycles, until n-1 edges are added where n is the number of nodes. The algorithm takes as input a weighted, connected graph and outputs the minimum spanning forest by iteratively selecting the lowest cost edge that avoids cycles.
The document outlines various data structures and algorithms for implementing dictionaries and hash tables, including:
- Separate chaining, which handles collisions by storing elements that hash to the same value in a linked list. Find, insert, and delete take average time of O(1).
- Open addressing techniques like linear probing and quadratic probing, which handle collisions by probing to alternate locations until an empty slot is found. These have faster search but slower inserts and deletes.
- Double hashing, which uses a second hash function to determine probe distances when collisions occur, reducing clustering compared to linear probing.
This document summarizes a talk on dynamic graph algorithms. It begins with an introduction to dynamic graph algorithms, which involve maintaining a graph structure and answering queries efficiently as the graph undergoes a sequence of edge insertions and deletions. It then discusses several examples of fully dynamic algorithms for problems like connectivity, minimum spanning trees, and graph spanners. A key data structure introduced is the Euler tour tree, which represents a dynamic tree as a one-dimensional structure to support efficient updates and queries. The document concludes by outlining a fully dynamic randomized algorithm for maintaining connectivity under edge updates with polylogarithmic update time, using a hierarchical approach with multiple levels of edge partitions and ET trees.

The document discusses greedy algorithms and provides examples of problems that can be solved using greedy techniques. It introduces the coin changing problem and activity selection problem. For activity selection, it demonstrates that a greedy approach of always selecting the activity with the earliest finish time results in an optimal solution. It provides pseudo-code for a greedy algorithm and proves that the greedy solution is optimal for the activity selection problem by showing there is always an optimal solution that makes the greedy choice and combining the greedy choice with the optimal solution to the remaining subproblem yields an optimal solution to the original problem.
The document discusses shortest path algorithms for weighted graphs. It introduces Dijkstra's algorithm and the Bellman-Ford algorithm for finding shortest paths. Dijkstra's algorithm works for graphs with non-negative edge weights, while Bellman-Ford can handle graphs with negative edge weights. The document also describes how to find shortest paths in directed acyclic graphs and compute all-pairs shortest paths.

Vr for education in korea conception and caseChoi Man Dream
This document discusses the use of virtual reality (VR) for education in Korea. It provides examples of how VR is being used in Korean classrooms to enhance empathy, immersion, and sustainability in learning. Specific cases described include using VR to learn about geography through Google Expedition, teach character education by simulating bullying, and conduct safety education through VR field trips. Teachers are using 360-degree video and VR apps like CoSpaces to record classes and create VR lessons. Students find VR lessons more engaging and fun compared to traditional book learning. The potential for VR in education is seen as endless, as it can support personalized learning experiences for all.
