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
