The first documented case of HyperNEAT producing a modular phenotype is presented, but the inability to encourage modularity on harder problems where modularity would have been beneficial suggests that more work is needed to increase the likelihood that Hyper NEAT and similar algorithms produce modular ANNs in response to challenging, decomposable problems.
HybrID: A Hybridization of Indirect and Direct Encodings for Evolutionary Computation

A new algorithm is proposed, a Hybridized Indirect and Direct encoding (HybrID), which discovers the regularity of a problem with an indirect encoding and accounts for irregularities via a direct encoding, suggesting that hybridizing indirect and direct encodings can be an effective way to improve the performance of evolutionary algorithms.
