At the end of this learning unit, the student is able to :

Given the learning outcomes of the "Bachelor in Engineering" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • S1.I1, S1.G1
  • S2.2
Students who have successfully completed this course will be able to:
  • Use the terminology of functions, relationships and together well and perform related operations when the context requires it
  • Explain the basic structure of the main proof techniques (direct proof, counterexample, proof by the absurd, induction, recurrence)
  • Apply the various proof techniques in a convincing way by selecting the most adapted to the problem posed
  • Analyze a problem to determine the underlying recurrence relationships
  • Calculate counts, permutations, arrangements on sets as part of an application.
  • Modeling various real-world problems encountered in computer science using the appropriate forms of graphs
  • Explain the problem of the shortest path in a graph and apply classical algorithms to solve this problem

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

About 30 hours of lectures, on-site or remotely depending on the situation.
A mandatory project/case study on the implementation of an algorithm.
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

A mandatory project/case study that counts for 2 out of 20 points. If the project report is not done (no report submitted), the student will not be allowed to pass the exam.
A written exam organized in session counting for 18 out of 20 points. Organized on-site or remotely, depending on the health situation.
