1-semester course
Inverse Problems, Identification and Optimization
for Masters Program Computational Mechanics and Biomechanics.
4 ECTS Credits
Aim of the course
The mathematical modeling in mechanics and biomechanics is typically faced with
direct and inverse problems. An inverse problem is a general framework that is used to
convert observed measurements into information about a physical object or system that we
are interested in. The reason is that many parameters are unknown a priori, and after some
measurements have been done they may be restored as a result of a certain inverse
problem solution. This theory is thoroughly connected with identification and optimization
problems. All of them require specific mathematical techniques, which are the basic goal
of the present lecture course.
Also this course analyzed the program coding techniques in C++ for the efficient
numerical solution of problems in science and engineering.

Techniques, Skills, etc.
After completing the course, the students are expected to be able to:

distinguish inverse and direct problems;

compare different approaches to the inverse problems, identification and
optimization;

choose and implement a suitable approach for a given problem;

ascertain basic properties of continuous and discrete problems and analyze
their correlations;

understand and analyze the stability of a method applied;

develop their own C++ code to solve typical inverse, identification and
optimization problems;

present coherent arguments to answer questions both orally and in writing.
Teaching
The following methods and forms of study are used in the course:

Lectures

Labs

Problem sets

Program coding

Self-study

Use of different reference books and Internet resources
At the end of the course the students are supposed to do problem sets and write a
report, make an oral presentation and participate in discussion. Upon the successful
completion, the students will gain 4 credits.
