Comes in two versions the standard and professional.
Pro version provides more control over training and better analysis tools.
Each comes with a comprehensive 324 page book, Introduction to Neural Networks which contains theory, tutorials and sample network applications. Available for DOS, Windows and Mac. Following Darwin's theories of genetic mutation and natural selection, GTO automatically creates a large number of subtly different networks to do the same job. GTO then trains, tests and ranks them to find the ANNs that perform the best overall. Available for DOS and Windows.
