who is taking the Stanford ai-class with Peter Norvig and Sebastian Thrun?

They are all data-modifying programs.

This is the same in CL. When you have a GP system that constructs new
program trees then inside your fitness function you

Nice. I'm glad these other classes are getting the full treatment.
It's really a shame they don't do a clearer job of defining the

understand the class. I find it diff

Hmm, I don't know if people will ever see Lisp as an "AI Language" though
(kidding). My personal experience was that I learned Common Lisp in the
context of an AI course in college. I was pretty excited about learning the
language, so I read The Little Lisper the summer before taking the course.
I think we all agree that Lisp would be ideal for AI, given a medium
or long-term exposure, but for an introductory class to varied
branches of AI, we could do worse than Python, an easy to read
language with various numerical and AI libraries (PyEvolve, for
example. http://pyevolve.sourceforge.net
Uau! That was a very comprehensive answer.
I was not expecting it.
Please note that you don't need to argue for Lisp to me, I also
enjoy the language quite much. Unfortunately the closest I get to
use Lisp based languages on the job are Emacs and Gimp macros.

I guess that nowadays many AI systems are mainly programmed in
some kind of specialized DSL.
Sure Lisp based languages are a perfect candidate for it, but the
plain
mention of Lisp brings up some issues that you cannot get rid of, like
the parenthesis.
To be honest, while I was at the university
I'm just concerned that teaching AI to 25K+ students is going to have an
impact and it shouldn't be because P. Norvig didn't publish the next edition
of AIMA. I wish they would realize that and change their mind on the
assignments for the class. Even Javascript is more suitable for AI than
Python!

I just can't figure out any example when there is a lot of sense to go the
self-modifying route.

Yes, if it slaps forms together and then executes (eval `(def ~sym

Here is an interesting question to ponder...
Learning involves permanent changes of behavior.
In AI this is often modeled as a self-modifying program.
The easiest way to see this would be a program that handles
a rubics cube problem. Initially it only knows some general
rules for manipulation, so

I agree with most of what you said, but not this.
There's a big difference bet
But it could also mean that you are expected to learn Python while taking
the class.
