Main themes
  • Computability : problems and algorithms, computable and non computable functions, reductions, undecidable classes of problems (Rice), fix point theorem, Church-Turing thesis
  •  Main computability models : Turing machines, recursive functions, lambda calculus, automates
  • Complexity theory : complexity classes, NP-completeness, Cook's theorem, how to solve NP-complete problems
Aims

Given the learning outcomes of the "Bachelor in Engineering" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:

  • AA1.1, AA1.2
  • AA2.4

Given the learning outcomes of the "Bachelor in Computer science" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:

  • S1.I3, S1.G1
  • S2.2

Students completing successfully this course will be able to

  • recognize, explain and identify the limits of computing science ;
  • explain the main computability models especially  their foundations, their similarities and their differences
  • identify, recognize and describe non computable and untractable problems

Students will have developed skills and operational methodology. In particular, they have developed their ability to

  • have a critical look at the performance and capabilities of computer systems

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
