Tools for Landscape Analysis of Optimisation Problems in Procedural Content Generation for Games

no code implementations16 Feb 2023 Vanessa Volz, Boris Naujoks, Pascal Kerschke, Tea Tusar

This way we aim to provide methods for the comparison of PCG approaches and eventually, increase the quality and practicality of generated content in industry.

Optimally Weighted Ensembles of Regression Models: Exact Weight Optimization and Applications

no code implementations22 Jun 2022 Patrick Echtenbruck, Martina Echtenbruck, Joost Batenburg, Thomas Bäck, Boris Naujoks, Michael Emmerich

More specifically, in this paper, a heuristic weight optimization, used in a preceding conference paper, is replaced by an exact optimization algorithm using convex quadratic programming.

Automating Speedrun Routing: Overview and Vision

no code implementations2 Jun 2021 Matthias Groß, Dietlind Zühlke, Boris Naujoks

The second part of this paper then refers to the actual speedrun routing optimization problem.

Towards Game-Playing AI Benchmarks via Performance Reporting Standards

no code implementations6 Jul 2020 Vanessa Volz, Boris Naujoks

While games have been used extensively as milestones to evaluate game-playing AI, there exists no standardised framework for reporting the obtained observations.

Towards Realistic Optimization Benchmarks: A Questionnaire on the Properties of Real-World Problems

no code implementations14 Apr 2020 Koen van der Blom, Timo M. Deist, Tea Tušar, Mariapia Marchi, Yusuke Nojima, Akira Oyama, Vanessa Volz, Boris Naujoks

This work aims to identify properties of real-world problems through a questionnaire on real-world single-, multi-, and many-objective optimization problems.

Expected Improvement versus Predicted Value in Surrogate-Based Optimization

1 code implementation9 Jan 2020 Frederik Rehbach, Martin Zaefferer, Boris Naujoks, Thomas Bartz-Beielstein

Few results from the literature show evidence, that under certain conditions, expected improvement may perform worse than something as simple as the predicted value of the surrogate model.

Surrogate-Assisted Partial Order-based Evolutionary Optimisation

no code implementations1 Nov 2016 Vanessa Volz, Günter Rudolph, Boris Naujoks

In this paper, we propose a novel approach (SAPEO) to support the survival selection process in multi-objective evolutionary algorithms with surrogate models - it dynamically chooses individuals to evaluate exactly based on the model uncertainty and the distinctness of the population.

Demonstrating the Feasibility of Automatic Game Balancing

no code implementations11 Mar 2016 Vanessa Volz, Günter Rudolph, Boris Naujoks

In this paper, the feasibility of automatic balancing using simulation- and deck-based objectives is investigated for the card game top trumps.
