Exercises for Chapter 14: Interactive EAs

  1. Navigate to an on-line resource such as picbreeder, or one of the many available implementations of Dawkins’ biomorphs. Experiment with trying to evolve first the simplest, and then the most complex figure you can. Are you able to draw any fixed rules about how to manipulate the underlying component-based representation?
  2. Find five different versions of the biomorphs program on the web, and devise your own experiment to see if the interface of the system affects for how long people are prepared to experiment with it.
  3. Write your own interactive EA for the simple task of selecting and ordering a set of ten letters to create a word – either new or existing. Then try and write down a series of rules that you might apply to reduce the number of solutions evaluated based on your experience of how words are formed.
