Description
Version: 3.0 start 01 February 2022
Short description
Students learn the basic terms and concepts used in theoretical computer science. They will also understand how to build models for assessing the performance of current and future computer systems: formal languages, automata theory and computational complexity

Learning objectives (competencies)
Objectives
Competences
Taxonomy levels
(1) They will acquire knowledge relating to the formal languages/grammatical systems, the types of automatas which use these and the relationships between them. They will be able to design automatas for given formal languages which will accept or define these languages, as well as design languages which given automatas can recognise and define.
(2) The students will be familiar with the major approaches used to formalise concepts of computability and those used to develop algorithms. They will be aware of the equivalences between these various approaches. They will know the concepts of decidable and semidecidable problems and will be aware of the relationship between these two types of problems.
(3) The students will know the most important classes of complexity – particularly P and NP – as well as the simple notations used to describe them (o notation and omega notation). They will understand the question of whether P=NP and be aware of its significance. They will be familiar with the polynomial reduction method and be able to apply it to comparatively simple examples.
Module contents
Motivation applicable to theoretical computer science:
formal calculation models
ability to recognise fundamental principles, irrespective of the hardware or software being used
the limits applicable to automatic calculations
Formal languages / machine theory:
fundamental definitions of formal languages
regular languages, finite-state machines (DFSM, NFSM, e-NFSM)
context-independent languages, pushdown automata
(recursive languages), Turing machines (TM)
Chomsky hierarchy
Computability and algorithm concept:
computable functions. Church’s thesis
Equivalence of TMs and computers
Computability and programming languages: GOTO, while and loop programmes
The algorithm concept
Primitive recursion
Non-decidability and decidability: Ld diagonal language, Rice’s theorem, busy beavers
Semi-decidable problems: halting problem, game of life, (Collatz numbers ?)
Reduction
Complexity theory
the complexity of algorithms
O-notation (omega-notation)
Polynomial and exponential functions
P class, NP class
NP-complete, NP-hard
Polynomial time reduction
