Introduction to Greedy Algorithms: Logic, Design, and Applications

When solving complex computational problems, finding the absolute best solution can sometimes take too much time and computing power. Greedy algorithms offer a powerful, intuitive approach by making the locally optimal choice at each step with the goal of finding a global optimum. This course guides you through the greedy paradigm, teaching you how to identify when a greedy strategy works, analyze its efficiency, and apply it to classic algorithmic challenges. What you'll learn: 1. Understand the fundamental principles of the greedy algorithmic paradigm and how it compares to dynamic programming. 2. Analyze classic greedy problems, including Huffman Coding, Fractional Knapsack, and Dijkstra's Shortest Path. 3. Evaluate the limitations of greedy choices and identify scenarios where they fail to produce the optimal global solution. 4. Practice designing greedy strategies with clean, modern Python implementations using type hints. 5. Determine the time and space complexity of greedy algorithms using Big O notation. You will start with core definitions and foundational concepts before moving on to step-by-step written walk-throughs of classic problems, analyzing how local decisions lead to global outcomes. This course is designed for beginner programmers and computer science students looking to strengthen their problem-solving skills, with no advanced mathematical background required.
