“Sequential Parameter Optimization for Mixed-Discrete Problems” Published in the Book “Optimization Under Uncertainty with Applications to Aerospace Engineering”

The book Optimization Under Uncertainty with Applications to Aerospace Engineering has recently been published in electronic and print format. It includes our contribution Sequential Parameter Optimization for Mixed-Discrete Problems (Lorenzo Gentile, Thomas Bartz-Beielstein, and Martin Zaefferer).

SPOT 2.3.0 is on CRAN

SPOT: Sequential Parameter Optimization Toolbox

SPOT, the Sequential Parameter Optimization Toolbox, is a set of tools for model-based optimization and tuning of algorithms. It includes surrogate models, optimizers, and design of experiment approaches. The main interface is spot, which uses sequentially updated surrogate models for the purpose of efficient optimization. The main goal is to ease the burden of objective function evaluations, when a single evaluation requires a significant amount of resources.

Version 2.30 of the R package SPOT will be published in the corresponding CRAN directory,see https://cran.r-project.org/package=SPOT

Survey “Benchmarking in Optimization: Best Practice and Open Issues” available

This survey compiles ideas and recommendations from more than a dozen
researchers with different backgrounds and from different institutes around the
world. Promoting best practice in benchmarking is its main goal. The article
discusses eight essential topics in benchmarking: clearly stated goals, well-
specified problems, suitable algorithms, adequate performance measures,
thoughtful analysis, effective and efficient designs, comprehensible
presentations, and guaranteed reproducibility. The final goal is to provide
well-accepted guidelines (rules) that might be useful for authors and
reviewers. As benchmarking in optimization is an active and evolving field of
research this manuscript is meant to co-evolve over time by means of periodic
updates.

The PDF version of this survey is available here and will be published on arXiv soon.

Aus SPOTSeven wird IDE+A


Im April 2018 wurde das Institut für Data Science, Analytics, and Engineering (IDE+A) der TH Köln offiziell gegründet. Das IDE+A geht aus dem SPOTSeven Lab hervor.
Mehrere hundert Nachrichten aus dem SPOTSeven Lab wurden in den letzten Jahren auf dieser Webseite veröffentlicht. Mit der Reorganisation geht auch eine Änderung der Kommunikationskanäle einher: Da wir jetzt den Status eines Instituts erhalten haben, werden wir die offiziellen Seiten der TH Köln für unsere News verwenden und den SPOTSeven Lab Blog nicht weiter nutzen. Neuigkeiten aus dem SPOTSeven Lab (oder besser: dem Institut IDE+A) finden Sie ab sofort auf der folgenden Seite: https://idea.f10.th-koeln.de
Die SPOTSeven Lab Seite wird im Laufe des Jahres abgeschaltet.
Falls Sie Interesse an der Weiterentwicklung von SPOTSeven/IDE+A haben, sind Sie herzlich zur feierlichen Eröffnung des Instituts am 28.9.2018 eingeladen. Näheres finden Sie auf den IDE+A-Seiten. Beachten Sie bitte, das eine Anmeldung per Mail erforderlich ist.
