Скачать или смотреть Turing Machines + Decidability in 3 Hours (TM, Variants, Church-Turing, Decidability)

Here we do a livestream covering everything to do with Turing Machines and Decidability. We cover Turing Machines (and their formal definition), what a "high-level" problem description is, several variants of Turing Machines (nondeterministic, multitape, etc.), the importance and truth of the Church-Turing thesis, encodings of machines, and decidability problems involving DFAs and CFGs.
