### Design and Analysis of Algorithms (CSCI 5454)

This semester, I'm teaching a new course (for me) on the design, analysis and evaluation of computer algorithms. This is a graduate-level course and covers a lot of standard material in algorithms. My hope, however, is to also show the students how different strategies for algorithm design work (and sometimes don't work) and to introduce them to a number of more advanced topics and algorithms they might encounter out in industry.

For those of you interested in following along, here's a list of my lecture notes and the topics I've covered. I'll update this entry with the rest of the lectures, once they're up on the course webpage.

CSCI 5454 Design and Analysis of Algorithms

Algorithms are the heart of computer science, and their essential nature is to automate some aspect of the collecting, organizing and processing of information. Today, information of all kinds is increasingly available in enormous quantities. However, our ability to make sense of all this information, to manage, organize and search it, and to use it for practical purposes, e.g., self-driving cars, adaptive computation, search algorithms for the Internet or for social networks, artificial intelligence, and many scientific applications, relies on the design of efficient algorithms, that is, algorithms that are fast, use little memory and provide guarantees on their performance.

This graduate-level course will cover a selection of topics related to algorithm design and analysis. Topics will include divide and conquer algorithms, greedy algorithms, graph algorithms, algorithms for social networks, computational biology, optimization algorithms, randomized data structures and their analysis. We will not cover any of these topics exhaustively. Rather, the focus will be on algorithmic thinking, efficient solutions to practical problems and understanding algorithm performance. Advanced topics will cover a selection of modern algorithms, many of which come from real-world applications.
