What can you learn in this course?
With the help of this course, we want you to achieve the following learning outcomes:
- You can read and write the formal notation of a grammar and classify grammars with regard to the Chomsky hierarchy.
- You can eliminate epsilon productions from grammars.
- You can name operations that contextfree grammars are closed under.
- You can proof that a language is not contextfree.
- You can describe the idea and the mode of operation of pushdown automata.
- You can transfer contextfree grammars into pushdown automata.
