Study Notes

Algorithms

Definition

  • A set of instructions to solve a specific problem or perform a particular task
  • A well-defined procedure that takes some input and produces a corresponding output

Types of Algorithms

  • Recursive Algorithms: break down a problem into smaller sub-problems, solving each recursively until the solution is found
  • Dynamic Programming Algorithms: break down a problem into smaller sub-problems, solving each only once and storing the solutions to sub-problems to avoid redundant computation
  • Greedy Algorithms: make the optimal choice at each step, hoping to find a global optimum solution
  • Divide and Conquer Algorithms: break down a problem into smaller sub-problems, solving each recursively and combining the solutions to solve the original problem

Algorithm Design Techniques

  • Brute Force: try all possible solutions and choose the best one
  • Divide and Conquer: break down a problem into smaller sub-problems and solve each recursively
  • Dynamic Programming: break down a problem into smaller sub-problems, solving each only once and storing the solutions to sub-problems
  • Backtracking: try a solution and if it fails, backtrack and try another solution

Algorithm Analysis

  • Time Complexity: the amount of time an algorithm takes to complete, usually measured in terms of the number of operations performed
  • Space Complexity: the amount of memory an algorithm uses, usually measured in terms of the number of bytes required
  • Big O Notation: a way of expressing the time or space complexity of an algorithm, usually in terms of the number of operations performed or the amount of memory used

Famous Algorithms

  • Sorting Algorithms: Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort
  • Searching Algorithms: Linear Search, Binary Search
  • Graph Algorithms: Breadth-First Search (BFS), Depth-First Search (DFS), Dijkstra's Algorithm
