Recently, I began to write a program that demostrates memory
representation as a network of concepts. AI is a hobby of mine and I
just began to throw the program together. I didn't use the best style,
but it still should have worked. (You can guess what's coming next!)
It didn't! At the debug() call the program starts printing random
data. I am running Mac OS X 10.3 using XCode. Here is the file, I hope
it isn't too long. Thank you for your help.
