Título: | Space Mapping: Models, Sensitivities, and Trust-Regions Methods | Autor: | Vicente, Luís N. | Data: | 2003 | Citação: | Optimization and Engineering. 4:3 (2003) 159-175 | Resumo: | The goal of this paper is to organize some of the mathematical and algorithmic aspects of the space-mapping technique for continuous optimization with expensive function evaluations. First, we consider the mapping from the fine space to the coarse space when the models are vector-valued functions and when the space-mapping (nonlinear) least-squares residual is nonzero. We show how the sensitivities of the space mapping can be used to deal with space-mapping surrogates of the fine model. We derive a framework where it is possible to design globally convergent trust-region methods to minimize such fine-model surrogates. | URI: | https://hdl.handle.net/10316/7749 | DOI: | 10.1023/A:1023968629245 | Direitos: | openAccess |
