  • have an understanding of basic questions of computer science,
  • can formalize intuitive statements and analyze the models quantitatively and qualitatively,
  • know the classification of formal languages,
  • can apply mathematical principles and are proficient in formalisation methods,
  • understand the difference of Turing machines as computing machines and recognizers of languages,
  • have an understanding of formalizations of predictability and their implications: modelling and analysis techniques.
