Abstract

Inspired by Richard Lenski’s Long-Term Evolution Experiment, we use the quantised chaotic Mackey-Glass time series as a prolonged learning task for artificial intelligence in the form of steady state linear genetic programming using GPengine to reach up to 100 000 generations. Using two point crossover and point mutation we evolve programs of up to 4 million instructions. Typically finding hundreds of fitness improvements in the later stages of the runs.
