Query: Evolving Game Skill-Depth using General Video Game AI Agents   Most games have, or can be generalised to have, a number of parameters that
may be varied in order to provide instances of games that lead to very
different player experiences. The space of possible parameter settings can be
seen as a search space, and we can therefore use a Random Mutation Hill
Climbing algorithm or other search methods to find the parameter settings that
induce the best games. One of the hardest parts of this approach is defining a
suitable fitness function. In this paper we explore the possibility of using
one of a growing set of General Video Game AI agents to perform automatic
play-testing. This enables a very general approach to game evaluation based on
estimating the skill-depth of a game. Agent-based play-testing is
computationally expensive, so we compare two simple but efficient optimisation
algorithms: the Random Mutation Hill-Climber and the Multi-Armed Bandit Random
Mutation Hill-Climber. For the test game we use a space-battle game in order to
provide a suitable balance between simulation speed and potential skill-depth.
Results show that both algorithms are able to rapidly evolve game versions with
significant skill-depth, but that choosing a suitable resampling number is
essential in order to combat the effects of noise.
