MACROS 1.8 Released

DATADVANCE development team is pleased to announce the release of MACROS 1.8.

This release brings many new features, performance and stability improvements. A brief summary of new features is given below.

GTApprox

• Added surrogate model export to plain old C, Octave and MEX: constructed surrogate model can now be used completely without MACROS.
• Added new approximation technique - Response Surface Model.
• Added pre- and postprocessing capabilities which assists user to configure the tool to get the most accurate model using given data and to improve constructed surrogate model.
• Significantly enhanced quality of approximation of noisy functions with Gaussian Process technique.
• Added an optional parameter to specify the variance of response values in the training sample.
• Added response noise variance information to the internal validation output.
• Added method to calculate accuracy evaluation gradients.
• Fixed the strong dependency of internal validation results on the random seed.

GTOpt

• Implemented new internal solver algorithm (Sequential Quadratic Constraints Quadratic Programming) which further reduces the number of objective functions and constraints evaluations.
  
• Added Surrogate Based Optimization strategy.
  
• Added new globalization strategy based on lightweight version of Surrogate Based Optimization.
• Implemented batch mode which allows to evaluate objective functions and constraints in multiple design points simultaneously. 

GTDoE

• Added Adaptive Design of Experiments technique based on Gaussian Processes.
• Added Optimal Design technique.
  

Other changes

• Improved the support for non-English system locales.
• Added new usage examples.
• Regression tests results and details included into documentation.
