   IOSO Approximation Software

The “IOSO approximation” software allows you to interpolate data and create an approximation model as an executable file (* .exe). Interpolation is a method of constructing new data points within the range of a discrete set of known data points in the mathematical field of numerical analysis

  Multi-objective Optimization Software IOSO 3

  Main new features and improvements of IOSO 3

  • The ability to multi-user and multi-tasking program mode

  • Direct integration with Creo

  • New types of postprocessing tools (graphs and others) are now available

  • New feature of saving of all result files of different applications for Paretto-optimal points is available

 Main new features and improvements of IOSO 2.3

  • IOSO PM - unique parallel algorithm of optimization is now available

  • Direct integration with Concepts NREC Turboopt II,  ANSYS WB2,  FLOW-3D,  SolidWorks, FlowVision

  • Enumeration type parameters are now supported

  • New types of built-in functions (like Abs, Min, Max) enhancing possibilities of Synthetic parameters are now available

  • Procedures of project settings and the forms of result tables were sufficiently improved

    Distinctive features of IOSO optimization technology:

  • multiobjective optimization for large-dimensionality problems (up to 100 independent design variables and up to 100 constraints), which allows to reach the increase of efficiency up to 7 times higher than that of middle-dimensionality optimization tasks (20…40 design variables)

  • low expenditures for optimal solution search (reduction of the number of analysis code direct calls calls up to 20 times in comparison with traditional approaches and genetic algorithms (GA), depending on the complexity and dimensionality of the task)

  • full automatic optimization technology algorithms with easy to use procedure of task setting

  • the possibility to solve multidisciplinary optimization problems

  • multiobjective optimization for stochastic problems, having complex topology of objective and the large number of constraints. Now it is well-known that many methods are capable of solving the tasks having up to 10 - 20 variables, and it is not known the analogues to IOSO  optimizer that is designed for large-dimensional multiobjective tasks

  • solving all classes of optimization problems including stochastic, multiextreme and having non-differential peculiarities

  • Maximum use of the potential of multiprocessor systems and local area networks for reduce total time of solving optimization task

  • Efficient use of difficult-to-parallelize applications and computation models

  • Solution of complex problems which have to the present time been thought impracticable to target

   Single-objective Optimization Software IOSO NS GT 2.0

IOSO NS GT v.2.0 is the program package implementing IOSO Technology algorithms for a single-objective nonlinear optimization with a moderate number of design variables (up to 100).

High efficiency of the evolutionary self-organizing algorithm. The efficiency is guaranteed by internal adaptive choice of the algorithm suitable for each particular problem. This feature results in solving complex optimization problems with minimal number of evaluations of the system mathematical model

"... IOSO consists of two stages. In the first stage, an approximate model of the objective functions is created. In the second stage, this approximate model is optimized. IOSO incorporates evolutionary algorithms, and artificial neural networks with radial basis functions that are used to build the response surfaces. The idea is to use this metamodel (or approximate model) to perform a very reduced number of evaluations of the actual objective functions of the problem..." Details...
