Study Notes
Algorithm Efficiency
- Two main measures for the efficiency of an algorithm are time and space complexity
- Time complexity is measured by counting the number of key operations
- Space complexity is measured by counting the maximum memory needed by the algorithm
Complexity Theory
- Cases that exist in complexity theory: best case, worst case, and average case
- There is no null case in complexity theory
Problem Solving Strategies
- Dynamic programming is used to solve the 0/1 Knapsack problem
- Backtracking is a strategy that stops execution when it finds a solution, otherwise starts the problem from the top
- Divide and Conquer is a strategy used in algorithms like Merge Sort
- Greedy algorithms are used to solve problems like the Knapsack problem and Huffman Coding
Sorting Algorithms
- Sorting is not possible using the deletion method
- Insertion, Selection, and Exchange are all methods of sorting
Graph Algorithms
- Dijkstra's algorithm bears some similarity to BFS and Prim's algorithm
- Breadth-First Search scans all incident nodes along with their children
- BFS is often used to find the shortest path in unweighted graphs
- DFS is often used to find the shortest path in weighted graphs
Asymptotic Notation
- Big O notation is used to measure the upper bound of an algorithm's time complexity
- Omega (Ω) notation is used to measure the lower bound of an algorithm's time complexity
- Theta (Θ) notation is used to measure the tight bound of an algorithm's time complexity
Algorithm Design Techniques
- Dynamic programming is used to find all pairs of shortest distances in a graph
- Divide and Conquer is used to solve problems like Merge Sort
- Greedy algorithms are used to solve problems like Huffman Coding
Tree Data Structures
- A Binary Search Tree (BST) is a tree where each node has a value greater than every value in its left subtree and less than every value in its right subtree
- A Heap is a complete binary tree where each node is at least as large as its children
- A Binary Tree is a tree where each node has at most two children
Huffman Coding
- Huffman Coding is a method of encoding characters using variable-length codes
- The optimal Huffman code is determined by the frequencies of the characters in the alphabet
