\"\"<\/a>SACOBRA (Self-adjusting Constrained Optimization By Radial Basis Functions<\/strong>) is a project which aims at solving constrained expensive problems with very few function evalutions. Such problems arise for example in car design and car manufacturing when complicated and time-consuming simulations have to check whether a new design fulfills all safety and stability constraints.<\/p>\n

Our research uses surrogate modelling<\/strong>, mainly with the help of radial basis functions<\/strong>, but also with Kriging<\/strong> models, to allow optimization with very few function evaluations. Our real-valued and derivative-free optimizer takes special care to handle multiple constraints<\/strong> (equality or inequality) in parallel to the optimization goal.<\/p>\n

SACOBRA is also a software package which can be downloaded from this GitHub-URL<\/a><\/strong>\u00a0or from this CRAN-URL<\/a>.<\/p>\n

Application areas<\/strong>: optimization of wing profiles, crash simulations and weight optimization in automotive industries.<\/p>\n
