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

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