| Summary: | Recently, the growth of Artificial Intelligence (AI) has provided a set of effective techniques for designing
computer-based controllers to perform various tasks autonomously in game area, specifically to produce
intelligent optimal game controllers for playing video and computer games. This paper explores the use of the
competitive fitness strategy: K Random Opponents (KRO) in a multiobjective approach for evolving Artificial
Neural Networks (ANNs) that act as controllers for the Ms. Pac-man agent. The Pareto Archived Evolution
Strategy (PAES) algorithm is used to generate a Pareto optimal set of ANNs that optimize the conflicting
objectives of maximizing game scores and minimizing neural network complexity. Furthermore, an improved
version, namely PAESNet_KRO, is proposed, which incorporates in contrast to its predecessor KRO strategy.
The results are compared with PAESNet. From the discussions, it is found that PAESNet_KRO provides better
solutions than PAESNet. The PAESNet_KRO can evolve a set of nondominated solutions that cover the solutions
of PAESNet. |
