Analyze algorithm efficiency through asymptotic notations, including big-O, omega, and theta, to measure time and space across input sizes and orders of growth.
Learn how linear search traverses an array from first to last to locate a key, with best, worst, and average cases and O(n) time, O(1) space.
Master Quicksort, a divide-and-conquer algorithm using a pivot and partitioning to sort in place. Analyze its time complexity across best, average, and worst cases.
Explore the mergesort algorithm by dividing, sorting, and merging subarrays; analyze its n log n time and O(n) space complexity, and understand best, average, and worst cases.
Apply the greedy approach that builds a local optimal solution, guided by the greedy choice property and optimal substructure, using Prim's and Kruskal's for minimum spanning tree, and Dijkstra's algorithm.
Prim's algorithm finds the minimum spanning tree of a connected weighted graph by greedily adding the lowest-weight edges from an arbitrary vertex until all vertices are included.
Kruskal's algorithm finds a minimum spanning tree by sorting edges by weight and adding them if they don't form a cycle, using disjoint sets and output the minimum spanning tree.

This course introduces the fundamental principles of algorithm design and analysis. Students will learn how to approach computational problems by designing efficient algorithms and evaluating their performance. Emphasis will be placed on understanding different algorithmic strategies and their applications across various problem domains. The course also focuses on mathematical tools for analyzing the time and space complexity of algorithms, as well as the impact of different algorithm design paradigms. This course prepares students for advanced topics in computer science and equips them with problem-solving skills critical in both academic and professional environments.
The Design and Analysis of Algorithms course is crucial for several reasons:
1. Problem-Solving Skills:
Algorithms are at the core of solving computational problems. Understanding how to design and analyze algorithms equips students with the ability to approach complex problems in a structured and efficient manner.
2. Efficiency Optimization:
Not all solutions are created equal. Some approaches may solve a problem, but with suboptimal performance. This course teaches how to develop solutions that not only work but are efficient in terms of time and space, which is critical in real-world applications where resources are limited.
3. Critical Thinking:
Designing algorithms involves making trade-offs and selecting the right approach based on the problem’s constraints and requirements. This encourages critical thinking, as students must evaluate multiple strategies and understand their pros and cons.
4. Foundation for Advanced Computer Science Concepts:
Algorithms are foundational to other areas of computer science, such as artificial intelligence, machine learning, cryptography, and databases. Mastering algorithms provides the background necessary for understanding more advanced and specialized topics in computer science.
5. Industry Demand:
Many technical roles in software development, data science, and system design require a deep understanding of algorithms. Employers often look for candidates who can design efficient algorithms and optimize system performance, making this course highly relevant for career preparation.
6. Understanding Computational Limits:
The course also covers concepts like NP-completeness and computational intractability, which help students recognize the boundaries of what can be computed efficiently. This awareness is vital for problem scoping and feasibility analysis in both research and industry projects.
7. Cross-disciplinary Application:
Algorithms are not limited to computer science. They play an important role in disciplines such as biology (genome sequencing), economics (auction theory), operations research (optimization problems), and more. Learning algorithms allows students to apply computational thinking to a wide range of fields.
8. Structured Approach to Programming:
The course provides a structured methodology for programming by teaching systematic approaches to algorithm design. This improves students' programming skills, helping them to write clear, efficient, and bug-free code.
