Course objectives
Students should be able to understand and explain the rich heritage of models and abstractions that have arisen over the years, and to develop the students' capacity to form abstractions of their own and reason in terms of them.
Learning outcomes
At the end of the course students should be able to:
Demonstrate an in-depth understanding of theories, concepts and techniques in automata and their link to computation.
Develop abstract machines that demonstrate the properties of physical/SW systems and be able to specify the possible inputs, processes and outputs of these machines. Analyze the computational strengths and weaknesses of these machines.
Understand the concept of computability by manipulating these machines in order to demonstrate the properties of computational processes.
Practice techniques of program design and development by using abstract machines. Apply automata concepts and techniques in designing systems that address real world problems
  • Languages and grammars. Chomsky hierarchy.
  • Finite automata and regular grammars.
