Introductory lectures on Automata Theory and Formal Grammars. The emphasis is put on basic terminology and fundamental results. We study and highlight connections between the following formal models: finite-state and push-down automata (both deterministic and non-deterministic), Turing machines (including the halting problem), regular, context-free, and context-sensitive grammars.

The course gives an introduction to automata theory and formal languages. The students will learn the following formal models and their basic properties:

finite-state and push-down automata (both deterministic and non-deterministic), Turing machines (including the halting problem), regular, context-free, and context-sensitive grammars and languages.

The form of study verification is a credit and an exam. Obtaining credit first is a necessary condition for taking an exam, with the exception of early exam terms. The credit is granted by teachers leading the tutorials based on point evaluation of tests during the semester, possible homeworks, activity etc. The nature of study verification for the credit excludes the possibility of its repetition.

The exam consists of written and oral parts. The written part precedes the oral part. If the written part is evaluated as unsatisfactory, the exam ends as unsatisfactory without taking the oral part. If the oral part is evaluated as unsatisfactory, the student has to repeat both written and oral parts on the next exam term. Final exam grade is based on evaluation of both written and oral parts.

Examples of the written part from previous years are available on the course webpage.

Demands at oral part correspond to the syllabus of the course in the extend that has been presented on lectures.

We may expect that substantial part of credits and exams is performed remotely. Written part of the exam can be replaced by moodle test, oral part performed remotely. The details depend on the actual situation and you will be noticed on any change.

Lectures and exercises

Requirements to the exam -
Last update: Mgr. Marta Vomlelová, Ph.D. (27.04.2020)

Credits from exercises are a necessary condition to attend the final exam.

The final exam consists from a written part and a possible additional oral part. The exam will test the acquired understanding of the definitions, theorems, and algorithms presented during the course.

We may expect that substantial part of credits and exams is performed remotely. Written part of the exam can be replaced by moodle test, oral part performed remotely. The details depend on the actual situation and you will be noticed on any change.
