Acquis
d'apprentissage

A la fin de cette unité d’enseignement, l’étudiant est capable de :

1 Learning outcomes:
  • AA1.1, AA1.2, AA1.3
  • AA2.1
  • AA5.2, AA5.3
After this course, the student will be able to :
  1. Estimate the actual complexity of Nonlinear Optimization problems.
  2. Apply lower complexity bounds, which establish the limits of performance of optimization method.
  3. Explain the main principles for constructing the optimal methods for solving different types of minimization problems.
  4. Use the main problem classes (general nonlinear problems, smooth convex problems, nonsmooth convex problems, structural optimization ' polynomial-time interior-point methods).
  5. Understand the rate of convergence of the main optimization methods.
  6. Two testing computer projects give a possibility to compare the theoretical conclusions and predictions with real performance of minimization methods
Additional benefits :
  • Training in scientific English
  • Experience in solving difficult nonlinear optimization problems
 
Contenu
  • General problem of nonlinear optimization. Black-box concept. Iterative methods and analytical complexity. Gradient method and Newton method. Local complexity analysis.
  • Convex optimization: convex sets and functions; minimization of differentiable and non-differentiable convex functions; lower complexity bounds; optimal methods.
  • Interior-point methods: notion of self-concordant functions and barriers; path-following methods; structural optimization.
Méthodes d'enseignement
The course is given in 12-15 lectures. The computer projects are implemented by the students themselves with supporting consultations.
Modes d'évaluation
des acquis des étudiants
In the written exam (in English or French) there are four questions, one for each chapter of the course (up to 5 points for each question). The marks for the exam and the exercises are combined in the final mark.
