Active-set approaches are commonly used in algorithms for constrained numerical optimization. We propose that active-set techniques can beneficially be employed for evolutionary black-box optimization with explicit constraints and present an active-s

We aim to observe differences between surrogate model assisted covariance matrix adaptation evolution strategies applied to simple test problems. We propose a simple Gaussian process assisted strategy as a baseline. The performance of the algorithm i

With the development of high-dynamic-range images and tone mapping operators comes a need for image quality evaluation of tone mapped images. However, because of the significant difference in dynamic range between high-dynamic-range images and tone m

Surrogate models in black-box optimization can be exploited to different degrees. At one end of the spectrum, they can be used to provide inexpensive but inaccurate assessments of the quality of candidate solutions generated by the black-box optimiza

This paper investigates constraint-handling techniques used in nonelitist single-parent evolution strategies for the problem of maximizing a linear function with a single linear constraint. Two repair mechanisms are considered, and the analytical res

Surrogate models are employed in evolutionary algorithms to replace expensive objective function evaluations with cheaper though usually inaccurate estimates based on information gained in past iterations. Implications of the trade-off between comput

While many tone mapping operators have been proposed, tuning their parameters remains a challenging task. In this work, we present a parameter tuning algorithm that can optimize the parameters of tone mapping operators automatically by minimizing the

We consider the problem of solving constrained numerical optimization problems where the objective function is a black box, but the constraint functions are known explicitly. A recently proposed active-set approach implemented in an evolution strateg

Tone mapping is the process of transforming high dynamic range images for display on low dynamic range devices. While many tone mapping operators have been proposed, there is no single operator that generates optimal results under all conditions. Ble

We consider the task of determining the pose of a depth camera based on a single target depth image and a 3D model of the indoor environment that the image was taken in. We identify the quality of a pose estimate with summed differences between depth
