چکیده

This paper focuses on parameter search for multi-agent based models using evolutionary algorithms. Large numbers and variable dimensions of parameters require a search method which can efficiently handle a high dimensional search space. We are proposing the use of complexification as it emulates the natural way of evolution by starting with a small constrained search space and expanding it as the evolution progresses. We examined the effects of this method on an EA by evolving parameters for two multi-agent based models.

Evolving agent-based models using self-adaptive complexification

This paper focuses on parameter search for multi-agent based models using evolutionary algorithms. Large numbers and variable dimensions of parameters require an optimization method which can efficiently handle a high dimensional search space. We are proposing the use of complexification as it emulates the natural way of evolution by starting with a small constrained search space and expanding ...

A Comparative Analysis of Simplification and Complexification in the Evolution of Neural Network Topologies

Approaches to evolving the architectures of artificial neural networks have involved incrementally adding topological features (complexification), removing features (simplification), or both. We will present a comparative study of these dynamics, focusing on the domains of XOR and Tic-Tac-Toe, using NEAT (NeuroEvolution of Augmenting Topologies) as the starting point. Experimental comparisons a...

Heterogeneous complexification strategies robustly outperform homogeneous strategies for incremental evolution

The evolution of naturalistic, embodied agents and behaviours has been a long-standing goal of Artificial Life since the initial, impressive work of Karl Sims. Incremental evolution has been used extensively to improve the quality of evolutionary search in many complex, non-linear problem spaces. This work sets out to disambiguate the lexicon around incremental evolution, advocating the term en...

Evolution of Complexity

The evolution of complexity has been a central theme for Biology [2] and Artificial Life research [1]. It is generally agreed that complexity has increased in our universe, giving way to life, multi-cellularity, societies, and systems of higher complexities. However, the mechanisms behind the complexification and its relation to evolution are not well understood. Moreover complexification can b...
