Reducing the cost of energy of wave energy converters is key for the advancement of the
technology. The costs associated with the device structure show the highest potential to …

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 …

This article provides an overview of multi-fidelity modeling trends. Fidelity in modeling refers
to the level of detail and accuracy provided by a predictive model or simulation. Generally …

The use of statistical techniques to build approximations of expensive computer analysis
codes pervades much of today's engineering design. These statistical approximations, or …

Corrugation has long been seen as a simple and effective means of forming lightweight
structures with high anisotropic behaviour, stability under buckling load and energy …

In this paper, a structural truss mass optimization on size and shape is performed taking into
account frequency constraints. It is well-known that structural optimizations on shape and …

Deterministic optimum designs that are obtained without consideration of uncertainties could
lead to unreliable designs, therefore calling for reliability-based design optimization (RBDO) …

A fraudulent financial statement involves the intentional furnishing and/or publishing of false
information in it and this has become a severe economic and social problem. We consider …

Two methods of creating approximation models are compared through the calculation of the
modeling accuracy on test problems involving one, five, and ten independent variables …

Many real-world applications can be formulated as expensive multimodal optimization
problems (EMMOPs). When surrogate-assisted evolutionary algorithms (SAEAs) are …
