Applied Discrete Structures is an open-content discrete mathematics textbook written by Alan Doerr and Kenneth Levasseur. The current main text is listed as Version 3-12, dated May 2025. It is not a live course or bootcamp in the traditional sense, but rather a collection of textbook and teaching resources centered on discrete mathematics, offering online reading, a free PDF, print copies, and supporting materials such as flipped-classroom exercises, videos, Sage Cell pages, a wiki, source code, and errata.
The subject area is clearly focused on discrete mathematics. The main text lists a Full Version, Part 1 Fundamentals, and Part 2 Algebraic Structures, and mentions that a short chapter on probability will be added. The delivery format is primarily self-study and classroom adoption: online reading is free and recommended, the PDF can be downloaded for free, and print copies are available for purchase. There is also Active Applied Discrete Structures, designed for flipped-classroom reading assignments, with exercises drawn from the textbook, new problems, and externally sourced questions with attribution. There is no information about live classes, a structured recorded-course system, 1v1 tutoring, certificates, or formal credentials.
Its biggest strength is affordability: the online version and PDF are free, while print copies are priced by version. The full version costs $42 plus shipping, Part 1 costs $28 plus shipping, and Part 2 costs $20 plus shipping. The textbook uses the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 United States License, allowing sharing as long as the license terms are preserved. This makes it suitable for low-cost use by university instructors and students.
The advantages are that the content is open, the project is continuously maintained, and it is available in multiple formats. It is also supported by Runestone Academy, LibreTexts, GitHub source code, errata, and a blog, making it easier for instructors to integrate into their courses. The authors’ backgrounds are also relatively transparent; the text notes that Alan Doerr taught at UMass Lowell for 50 years. The limitation is that it is more of a textbook project than a complete online course: there is no clear learning-progress management, assignment grading, certificate, Chinese-language support, or dedicated customer service. For learners in China, English mathematical terminology and the prerequisite foundation in discrete mathematics may present a certain barrier.
It is suitable for university discrete mathematics courses, self-study by computer science or mathematics majors, and instructors who want to adopt an open textbook and flipped-classroom model. The source text does not provide information about access from China, so this remains unknown; it also does not specify the payment methods for print copies. If access is unstable or a Chinese-language alternative is needed, learners may consider domestic university open courses in discrete mathematics, Chinese discrete mathematics textbooks, or related open resources on LibreTexts and Runestone.
