Spent some time today thinking (and just recently talking) about ideas for further Jotto AI development. I ended up running my corrected AI algorithm on a smaller dictionary, and it appears to be quite a bit better than the dumb AI. When the algorithm has a possible word list lower than a certain size, it turns on. Before that, it just mimics the dumb AI. Right now, that size is set at 1000 in order to have the algorithm complete in a somewhat reasonable time. When the dictionary starts out at 12,000 words, there are 3-4 guesses before it gets down below 1000. The smaller dictionary has about 4,000 words, so there are only about 2 guesses before it gets down below 1,000. This leads me to believe that the algorithm might actually do really well without a size limit. Once I upgrade my computer, I might try running it on my computer, which I assume could be faster than jmac.org. I suppose I could also try translating the program into some other language (I'm guessing C) to speed up the execution time.

But the thinking I did today about the algorithm has it expanding into a neural network type of thing. I don't feel like going into the whole algorithm right now, but I'll just say that I'm thinking that an algorithm that has 6 parameters (and actually, maybe those 6 parameters would have different values when the possible word list is at different sizes, so there might actually be something like 30 parameters), and a neural network (if I understand it correctly, as I've never actually implemented a neural network) would be a good way to find (close to) optimal values for those parameters. And then, of course, there's look-ahead, like the chess-playing programs use. Combine those two approaches, and we're talking some serious CPU cycles, I think. And lots of iterations in order to find the (close to) optimal parameter values.

I don't imagine it will come as much surprise that I'm currently re-reading Godel, Escher, Bach. I have another Hofstadter book that I haven't read, Fluid Concepts and Creative Analogies, and I think I'm going to read that next. And then I'll probably get his Le Ton beau de Marot, which he talks about in the preface to the 20th anniversary edition of GEB. And probably his collection Metamagical Themas after that. Yes, I tend to get obsessed by an author, but it's nice that this one will also get me thinking more about creative things (programming and writing) instead of just escaping into a story.
