Abstract :
The author used J.R. Koza´s (1992) genetic programming to evolve programs that classified contiguous regions of proteins as being α-helix cores or not. He snipped positive and negative examples of α-helix core regions out of a set of 90 proteins. These proteins were chosen from the Brookhaven Protein Data Bank to be non-homologous. The fitness of the programs was defined as the correlation coefficient between the observed and the predicted α-helicity of the above regions. The fittest program produced by the genetic programming system that predicted the training set at least as well as the testing set had a correlation of 0.4818 between the observed classifications and the classifications predicted by the program (on the proteins in the testing set)
