The use of metamodeling techniques in the design and analysis of computer experiments
has progressed remarkably in the past 25 years, but how far has the field really come? This …

For many years all three of us have been interested in, and have tried to make contributions
to, derivative-free optimization. Our motivation for writing this book resulted from various …

Spatial optimization is an interdisciplinary field dedicated to the scientific and rational
allocation of resources spatially, which has received tremendous attention across various …

Objective functions that appear in engineering practice may come from measurements of
physical systems and, more often, from computer simulations. In many cases, optimization of …

Microwave CAD has its roots in the 1960s [1]. Its practice saw the enrichment of circuit-
based model libraries, advances in EM and circuit simulation accuracy, and the refinement …

Design of contemporary antenna structures heavily relies on electromagnetic (EM)
simulations. Accurate reflection and radiation responses of many antenna geometries can …

Modelling, simulation and optimization form an integrated part of modern design practice in
engineering and industry. Tremendous progress has been observed for all three …

Computer simulation models have become the most important design tools in the majority of
engineering disciplines. They are used for verification purposes but also directly in the …

A shape-preserving response prediction methodology for microwave design optimization is
introduced. The presented technique allows us to estimate the response of the microwave …

Convergence is a well-known issue for standard space-map** optimization algorithms. It
is heavily dependent on the choice of coarse model, as well as the space-map** …
