Optimization Software Operating System: Windows IOSO NS

Using IOSO NS, you can quickly and efficiently solve non-linear parametric optimization problem with dimensionality up to 5 independent variables and 5 functional inequality constraints. Family of IOSO NS versions utilizes set of heuristic self-organizing optimization algorithms. These algorithms are based on usage of owner-developed approximation technology. At every iteration of search for optimum response surfaces are being built for objective and constrained parameters, then these response surfaces are being optimized. Thus, the number of direct calls to mathematical model is minimized, and time expenditures for problem solution are also minimal. Using approximation technology makes it possible to solve successfully problems with complex topology of objective and constraints. Unlike the gradient methods, IOSO NS works robustly with discontinuous, non-differentiatable, noised and locally incomputable objectives and constraints.
