The Role of Receiver Error in Evolutionary Systems

抄録: Evolutionary computing allows for the creation of simulations to test theories and further our understanding of the natural world. One area of recent investigation is that of signalling systems; in nature, male signallers advertise their quality to female receivers, who in turn decide whether to accept or reject the possible mate.

Until now, simulations have used simple receiver reward functions that reward the receiver’s accuracy at guessing the signaller’s quality. This does not accurately represent the pressures faced by signal receivers in nature when choosing a mate, as the penalties associated with accepting a poor-quality mate are worse than those of rejecting a high-quality mate.

The project builds on a previous simulation model and implements three explicit fitness functions before moving to an implicit fitness system. Each of the functions are analysed and compared to previous work to determine their effectiveness, from which subsequent improved functions are devised.

It was found that by emulating the binary decision process present in nature, it was possible to use the decisions receivers make to implicitly define their fitness. This approach was more effective than previous explicit systems in emulating the difference of penalties in nature.
