[Reduce-algebra-developers] Turing off automatic simplification.

[Ted K. <ted...@gm...>]

This past May I submitted the following question to the Reduce forum
which was about turning off automatic simplification:

http://sourceforge.net/projects/reduce-algebra/forums/forum/899364/topic/4499010

The revalp code that Tony submitted provides a partial solution, but a
full solution would allow functions like NUM, DEN, and SUB to be used
on the expression so that it can be analysed and manipulated. At one
point I thought that I could add this feature myself, but I found that
I will have to study Rlisp further before I have the skills needed to
do it properly.

I am asking for this capability on behalf of the GeoGebra project
(http://GeoGebra.org) because they are in the process of adopting the
Java version of Reduce as the CAS computation engine for GeoGebra. By
the way, GeoGebra has millions of users worldwide and its level of
adoption continues to increase. They are very excited about the idea
of using the commercial-quality Reduce CAS as the computation engine
for GeoGebra and their plan is to ship Reduce with the new GeoGebra
4.0 in August.

I have asked Simon Weitzhofer, who is a GeoGebra developer, to join
this email list so that he can provide more information on the
no-simplification feature that they need for GeoGebra. I am hoping
that this feature can be added to Reduce without too much difficulty.

Thanks,

Ted
