Study Notes

Algorithmic Complexity

  • Measures resources (time, memory) needed for an algorithm to solve a problem.
  • Compares algorithm efficiency.
  • Predicts how runtime scales with input size.

Key Concepts

  • Time Complexity: Algorithm runtime as a function of input length.
  • Space Complexity: Memory space required by an algorithm as a function of input length.
  • Big O Notation: Classifies algorithms by growth rate of runtime or space needs as input grows, focusing on the upper bound.
    • O(1): Constant time
    • O(log n): Logarithmic time
    • O(n): Linear time
    • O(n log n): Linearithmic time
    • O(n^2): Quadratic time
    • O(2^n): Exponential time
    • O(n!): Factorial time

Determining Algorithmic Complexity

  • Identify the Dominant Operation: Find most frequently executed operation.
  • Analyze Executions: Count how often the operation runs relative to input size.
  • Express with Big O: Represent upper bound of growth rate using Big O notation.

Big O Code Example

  • The dominant operation in the python code provided is the comparison element == target.
  • The time complexity is $O(n)$ in the worst case scenario because we iterate over all nn elements of the array.

Common Algorithmic Complexities

  • O(1) Constant: Accessing an array element by index.
  • O(log n) Logarithmic: Binary search.
  • O(n) Linear: Linear search.
  • O(n log n) Linearithmic: Merge sort, quicksort.
  • O(n^2) Quadratic: Bubble sort, insertion sort.
  • O(2^n) Exponential: Tower of Hanoi.
  • O(n!) Factorial: Traveling salesman problem (brute force).

Importance

  • Choosing the Right Algorithm: Select the most efficient one.
  • Performance Optimization: identify bottlenecks for better performance.
  • Scalability: Handle large inputs efficiently.
  • Analyzing complexity leads to efficient, scalable code and improved software performance.
