How the world was MADE: parametrisation of evolved agent-based models for backstory generation

Our paper “How the world was MADE: parametrisation of evolved agent-based models for backstory generation” has been accepted in Evostar 2015 conference. This paper continues our previous work published at ALIFE. You can also download the MADE framework source and binaries to test it for your own. Also, read the draft in our repository on GitHub.

The abstract:

Generating fiction environments for a multi-agent system optimized by genetic algorithms (with some specific requirements related to the desirable plots), presents two main problems: first it is impossible to know in advance the optimal value for the particular designed fitness function, and at the same time, it creates a vast search space for the parameters that it needs. The purpose of this paper is to define a methodology to find the best parameter values for both, the evolutionary algorithm, and the own fictional world configuration. This design includes running, to completion, a world simulation represented as a chromosome, and assigning a fitness to it, thus composing a very complex fitness landscape.

In order to optimize the resources allocated to evolution and to have some guarantees that the final result will be close to the optimum, we systematically analyse a set of possible values of the most relevant parameters, obtaining a set of generic rules. These rules, when applied to the plot requisites, and thus, to the fitness function, will lead to a reduced range of parameter values that will help the storyteller to create optimal worlds with a reduced computation budget.
