I am interested in evry kind of documentationon lisp so if you can ofer something... More than the language it self, lisp ofer a variety of dialects (scheme) or other like it. I remember that I don't know at all tcl/tk, but with my lisp knowledge I was able to debug a program in tcl/tk. So if you have any good book on lisp and you are so kind to share it with me, i wait for it. 

I use lisp in my programming job.
best regards

To comment a little on this.

Lisp is not a functional programming language. It supports a myriad of
programming styles which is why it has survived and thrived in some
instances for over 50 years.

Lisp supports functional, procedural, logical, aspect oriented, and object
oriented styles just to name a very small few.

Also, it is truly a wonderful language. In less than 300 lines of code, I
was able to write a distributed evolutionary algorithm to do the class of
traveling salesman like problems efficiently and quite nicely.
As another example, the entire prolog language was implmented in lisp in the 
back of my introduction to lisp book, for example. Some of the three and
five liners in lisp are truly mind blowing.

*chuckling*, and folks think I'm a java guy, *snicker*, man do I have them
fooled.

I wish I had an opportunity to use lisp on a daily basis.

Take care,
Sina

You can make A.I. even with visual c#, but you must make a lot of code.
There are other programming paradigms more dedicated to this.
1. Functional programming (represented by lisp/scheme)
2. Logical programming (represented by prolog)

for example a gcd calculation in prolog will look like:
gcd(x,0,X).
gcd(X,Y,D):-R is X MOD Y,gcd(Y,R,D).

Thats all
now you can make
gcd(15,5,X).
and in d you will have the result.
Compare this with a traditional procedural/oop programming euclid algorithm 
and you will see the benefits.
For having A.I. is necessary to have the learning capability in your
software
that means that a method have to change is behavior from a calling to
another.
To be more explicit let say we have a method that receive 2 parameters
x and y to integers
at first call the method returns the sum of the two numbers.
Some where in time at another call the same method with same parameters have 
to return the product of the two integers.
that according to some lines which are between those two calls.
And this change in behavior must be not predictiv
so you can not do an if in the method and according to an conditon return
either the sum or the product.
For this situation functional programming respond better than other
paradigms.
Because in a functional programming language you can modify the body of a
function easy from call to call.
in c# in dotnet 2.0 this is posible only using reflection.
dotnet 3.0 introduced 2 new things that I like very much
1. linq
2. f#

Also you can find on the net libraries written for c# used to interpret
lisp/prolog.
I worked with some of them in time to get faster results.

best regards.

Hi Guys:
Just looking at overviews of how Neural Networks are used to predict
Stock Market movements. Is the AI done an any language like Vb.net or are
there specific Programming languages used here. I am just looking at the
possibilities to see if my programming and math knowledge would allow me to 
play with them some.
I have a good background in math, stats and Vb.net and can, of
course, learn other things if necessary but what might they be?
