Tools for Landscape Analysis of Optimisation Problems in Procedural Content Generation for Games
The term Procedural Content Generation (PCG) refers to the (semi-)automatic
generation of game content by algorithmic means, and its methods are becoming
increasingly popular in game-oriented research and industry. A special class of
these methods, which is commonly known as search-based PCG, treats the given
task as an optimisation problem. Such problems are predominantly tackled by
evolutionary algorithms.
We will demonstrate in this paper that obtaining more information about the
defined optimisation problem can substantially improve our understanding of how
to approach the generation of content. To do so, we present and discuss three
efficient analysis tools, namely diagonal walks, the estimation of high-level
properties, as well as problem similarity measures. We discuss the purpose of
each of the considered methods in the context of PCG and provide guidelines for
the interpretation of the results received. 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.Comment: 30 pages, 8 figures, accepted for publication in Applied Soft
