Open textbook Theory of Computing: A Gentle Guide to Formal Languages and Computability

burkov · x · 2026-10-10

ML author Andriy Burkov recommends the open-access textbook "Theory of Computing: An Open Introduction" (Taylor J. Smith, 2024), calling it a must-read for anyone serious about computer science.

Aimed at undergraduates and instructors, the book assumes basic math and CS thinking, with an appendix covering sets, relations, functions, sequences, and graphs. It focuses on formal languages, abstract automata, and computability theory — what idealized computational models can do when freed from physical limits like finite memory — rather than a Boolean-circuit engineering approach.
