abstract = "The reward functions that drive reinforcement learning
systems are generally derived directly from the
descriptions of the problems that the systems are being
used to solve. In some problem domains, however,
alternative reward functions may allow systems to learn
more quickly or more effectively. Here we describe work
on the use of genetic programming to find novel reward
functions that improve learning system performance. We
briefly present the core concepts of our approach, our
motivations in developing it, and reasons to believe
that the approach has promise for the production of
highly successful adaptive technologies. Experimental
results are presented and analysed in our full report
[3].",
