Using a Net to Catch a Mate: Evolving CTRNNs for the Dowry Problem
Elio Tuci, Inman R. Harvey, Peter M. Todd · The MIT Press eBooks · 2002
Choosing one option from a sequence of possibilities seen one at a time is a common problem facing agents whenever resources, such as mates or habitats, are distributed in time or space. Optimal algorithms have been developed for solving a form of this sequential search task known as the Dowry Problem (finding the highest dowry in a sequence of 100 values); here we explore whether continuous time recurrent neural networks (CTRNNs) can be evolved to perform adaptively in Dowry Problem scenarios, as an example of minimally cognitive behavior [Beer, 1996]. We show that even a 4-neuron CTRNN can successfully solve this sequential search problem, and we offer some initial analysis of how they can achieve this feat.
