Mastering Algorithm Efficiency: Big O Notation Unveiled
Slide 1 - Diapositive
Learning Objective
Understand measures and methods to determine the efficiency of different algorithms, and grasp the concept of Big O notation including constant, linear, polynomial, exponential, and logarithmic complexity.
Slide 2 - Diapositive
What do you already know about algorithm efficiency and Big O notation?
Slide 3 - Carte mentale
Algorithm Efficiency
Efficiency is crucial in computer science. It involves measuring the performance and resource usage of algorithms. We will explore different measures and methods to assess efficiency.
Slide 4 - Diapositive
Measuring Efficiency
Efficiency can be measured using time complexity and space complexity. Time complexity examines the time taken by an algorithm, while space complexity evaluates the amount of memory used.
Slide 5 - Diapositive
Big O Notation
Big O notation is used to describe the upper bound of an algorithm's time or space complexity. It helps us understand how the algorithm's performance scales with input size.
Slide 6 - Diapositive
Constant Complexity
An algorithm has constant complexity (O(1)) if its performance does not depend on the input size. It executes in constant time.
Slide 7 - Diapositive
Linear Complexity
An algorithm has linear complexity (O(n)) if its performance scales linearly with the input size. It executes in time proportional to the input size.
Slide 8 - Diapositive
Polynomial Complexity
Algorithms with polynomial complexity (O(n^k)) have performance that scales with the input size to the power of k. Common examples include O(n^2) and O(n^3).
Slide 9 - Diapositive
Exponential Complexity
Exponential complexity (O(2^n)) signifies performance that grows exponentially with the input size, making it highly inefficient for large inputs.
Slide 10 - Diapositive
Logarithmic Complexity
Algorithms with logarithmic complexity (O(log n)) exhibit performance that grows logarithmically with the input size, making them highly efficient for large inputs.
Slide 11 - Diapositive
Practical Application
Apply the knowledge of algorithm efficiency and Big O notation to analyze and compare the performance of different algorithms in real-world scenarios.
