Global Optimization Group

Keywords: Optimization, global optimizaton, multi-objective optimization, parallel computing, high-performance computing, data analysis and visualization

The research group develops algorithms for global and multiobjective optimization and their parallel versions for highperformance computers, applies optimization to solve practical problems in engineering, science, business and medicine.

Research group activities

Global optimization is the search for the minimum of a function when there may be many local minima and most of them are not useful for a decision maker, only the global minimum matters. Differently from local optimization where optimality conditions may be used to show that the optimization problem is solved, in global optimization local information about the solutions is not enough and different solution strategies must be used to search for the global minimum. Global optimization problems are computationally expensive and difficult to solve. When computing power of usual computers is not enough to solve such problems, high-performance computers and clusters of computers are used. Therefore, parallel versions of optimization algorithms are developed and applied to solve large practical problems.

Proposal

  • optimization of technological processes, engineering constructions, etc.;
  • implementation of software for optimization, multidimensional data analysis and visualization;
  • parallelization of algorithms.
