GTApprox: surrogate modeling for industrial design
This tool addresses surrogate modeling needs for industrial design, but it appears incremental with novel algorithms and options built on existing methods.
The authors tackled the problem of surrogate modeling for industrial design by introducing GTApprox, a tool that demonstrates efficiency on a large collection of test problems and real engineering applications.
We describe GTApprox - a new tool for medium-scale surrogate modeling in industrial design. Compared to existing software, GTApprox brings several innovations: a few novel approximation algorithms, several advanced methods of automated model selection, novel options in the form of hints. We demonstrate the efficiency of GTApprox on a large collection of test problems. In addition, we describe several applications of GTApprox to real engineering problems.
