I have been working on a program that is similar to the program used in Dawkins book.  Random inputed letters are converted in to a numerical format, and than randomized and loop until the word DARWIN is on the screen.  the program is being written on a ti 89 titanium.    

Interesting...

It is done

There are three versions of this program that I have written.   The first on was TOBEOR and took about an hour to program.  Based of of TOBEOR was RANDGENE and it added my APLPHA coding to make use of Julian cryptograms.  It took about 5 hours to program and the first time I ran it, it had no errors.  Nice luck there, eh?  The latest is GENETEST and it took about 8 hours to program and was full of errors. They all "evolve" the word "darwin" from a set of random numbers.  TOBEOR and RANDGENE use brute calculation to do it, while GENETEST uses "evolution" to reduct the number of errors and generations, but it has more steps so it takes about the same amount of time as RANDGENE.

My current project is to use RANDMATX, a random matrix generator I built, to create a evolving shape on the graph screen.  It will start as a random point and turn into a "cell", a "frog" and a "human" along with a spiral somewhere as a TTGL reference.   It will be a while before it is done though.  All of this is done on my TI 89 titanium.  This last program will have probably three parts as well.
