A Study on Fitness Functions and Their Impact in PCG

Sammanfattning: Procedural Content Generation (PCG) is a tool for developers to take advantage of the computational power of the computer in order to create new content. There are many different method that a PCG program is able to utilize but finding the most optimal may be very challenging. In this paper we improved Evolution Dungeon Designer (EDD) by integrate symmetry and similar fitness function. We evaluated them with experiments and a user study that involved participants that are active in the field of game development. We can see that both symmetry and similar functions can easily be integrated for creating 2D dungeon rooms but has the potential of overwhelm the existing functions.
