This looks extremely interesting and will take me a while to digest. I am wondering if you have already done what I am working on? I’m taking an expert system, rather than neural net approach to finding likely solutions to eternagame puzzles. I have always thought that the best thing was to combine the two, but that is not easily done.
I can see that you have done a lot along the lines of “give me a sequence and I will predict the structure.” I am not yet clear on whether you have done “give me a structure and I will predict one or more sequences that will produce it.”
