3. Digital processing of signals and images.
4. Equations solution.
5. System analysis, optimization, mathematical programming, decision-making techniques.
6. Information security methods.
7. Applied problems.

  • the construction of the guaranteed upper-bound estimates of quality of the problem approximate solution;
  • the construction of the lower-bound estimates of the accuracy and processing speed of typical problems of computational mathematics;
  • the identification and clarification of apriori information about the problem;
  • the construction of optimal and asymptotically optimal algorithms of accuracy and processing speed for solving typical problems of computational mathematics;
  • the construction of optimal estimates taking into account the choice of the best information operator for this class of problems;
  • the construction of effective algorithms for solving typical classes of problems of computational and applied mathematics in different computing models: sequential, parallel, quantum, optical, in the system of residual classes;
  • the construction of provably resistant cryptographic and steganographic systems;
  • testing of algorithms-programs quality;
  • the construction of computer technologies for solving problems of applied and computational mathematics with given values of quality characteristics for accuracy and processing speed.

The conference presupposes delivering scientific reports, discussions and contest for the young scientist's best report.
