15-451/651 Algorithms Carnegie Mellon University Spring 2022 This course explores the design and analysis of algorithms, algorithmic modelling techniques, and their efficiency. It aims to provide tools for designing and analyzing personal algorithms, using various analytical tools and frameworks. Some advanced topics not commonly covered in textbooks are also taught. This course is about the design and analysis of algorithms. We will study specific algorithms for a variety of problems, as well as powerful modelling techniques (e.g. graphs and linear programming) and design paradigms (e.g. amortized analysis, dynamic programming, and sweep-line). (The complete list of topics is on the "Home/Schedule" page linked above.) We will study ways to analyze the efficiency of algorithms, and give lower bounds on the complexity of a problem. The topics have been chosen for their power, beauty, and practicality. The main goal of this course is to provide the intellectual tools needed for designing and analyzing your own algorithms for new problems you need to solve in the future. By the end of this course, you should be able to:

- Use and explain algorithm design tools discussed including divide-and-conquer, balanced search trees, hashing, graphs, randomization, dynamic programming, network flows, and linear programming, as well as basic data structure and algorithm design principles.
- Use and explain analytical tools and frameworks discussed including recurrences, probabilistic Analysis, minimax optimality, amortized analysis, analysis within different concrete models, and potential functions.
- Identify and critique incorrect analyses, find counterexamples to faulty claims and "proofs" of correctness.  - Several of the topics we teach, particularly the more advanced ones, are not covered in the standard Algorithms textbooks. Hence we will provide lecture notes covering all the material in this course.
- However, we would like you to have a book to give you more detailed coverage. (Or to give you an alternative perspective if you find our own confusing!) We recommend you get one of the following:
    - Introduction to Algorithms, by Cormen, Leiserson, Rivest, and Stein (hereafter referred to as "CLRS"). It's big, it's fairly expensive, but it is the gold standard of algorithms books with a lot of material. Based on the Algorithms course at MIT.
   - Algorithms, by Dasgupta, Papadimitriou, and Vazirani (herafter referred to as "DPV"). Smaller, cheaper, more informal. A relatively new book based on Algorithms courses at UC Berkeley and UCSD. A preliminary (incomplete) version is available here.
Specific readings in CLRS and DPV will be listed on the course schedule. It is recommended that you skim the reading before lecture, with a more thorough read afterwards.
- Other helpful material can be found in: Algorithm Design by J. Kleinberg and E. Tardos, Data Structures and Network Algorithms by R. E. Tarjan, Randomized Algorithms by Motwani and Raghavan, Programming Pearls by J. Bentley, Introduction to Algorithms: a Creative Approach by U. Manber, and the classic Aho-Hopcroft-Ullman book. See also some excellent lecture notes by Jeff Erickson at UIUC.
