Incompatible genes

[Lunderberg]

Currently, we handle shared genes, and unshared genes. There is a third category that we should be considering as well, that of incompatible genes. These would be genes that have the same origin/destination, but have different history, and therefore different innovation numbers. They can't be merged together easily, and cannot both exist in the resulting net, so they are in conflict.

An example would be where two new connections could be made, A and B. In one branch of a family tree, first A then B is made, while in another, first B then A is made. These have different histories, and so they cannot be properly merged.
