Center node: "learning fitness functions for genetic algorithms"
  Abstract: A genetic algorithm (GA) attempts to solve a problem using a pool of potential solutions that are iteratively refined using various selection techniques. Although GAs have been used successfully for many problems, one criticism is that hand-crafting a GA's fitness function, the test that aims to effectively guide its evolution, can be notably challenging. Moreover, the complexity of a GA's fitness function tends to grow proportionally with the complexity of the problem being solved. #R##N#In this work, we present a novel approach to learn a GA's fitness function. For the purpose of simplicity, we limit the demonstration of this technique to automatic software program generation. However, our system has no specific restrictions that prevent it from being applied to other domains. #R##N#We also augment the GA evolutionary process with a minimally intrusive search heuristic. This heuristic improves the GA's ability to discover correct programs from ones that are approximately correct and does so with negligible computational overhead. We compare our approach to two state-of-the-art program generation systems and demonstrate that it finds more correct programs with fewer candidate program generations.
