The second project was going to be using Lisp on the Apple II to do curve fitting via genetic programming. I was planning on using P-Lisp from 1982 but the memory space it so limited that I don't believe I'll get good results. So, instead, I'm going to use particle swarm optimization in Lisp to do the curve fitting. This is a genetic algorithm and I've used it several times before for just this task, but on more powerful computers, of course!
If I get the curve fitting done to my satisfaction, I might try implementing an interface on the Apple II for the DI-194RS, a cheap 4-channel 10-bit A/D box. I have an implementation on my home page in Python already. This will be in Forth and/or Lisp. Check out specific progress on each project:
