Genetic Programming Anyone?

[Martin Hepperle]

Namir,

while not running on an HP calculator I have used a program which was intially called "Eureqa" (like the old Borland math tool) and now sails under the name "Nutonian formulize"
(see http://www.nutonian.com/).
This is a handy tool to create analytical approximations of data sets. It constructs and evaluates equations from basic building blocks using a genetic algorthm. You can watch it at work and finally select a compromise between accuracy and complexity for your approximation equation. Maybe you can get some ideas for an implementation on a calculator. I would expect rather high memory requirements though.
