Hi Stef, I will be very happy to release my Simplex application; I developed it some years ago in VSE. At present I am trying to port under Pharo (or Squeak) an expert system generator based on fuzzy logic which name is FuzzyWorld and I have already used for lot of real word applications. I attach some documentation about a presentation I had at ESUG and of current version of FuzzyWorld. An initial version of FuzzyWorld has been already ported by a student of mine (Davide Arrigo)to Squeak; I am sure he will pleased to release it. Please, tell what I have to do for releasing them.

I was refactoring for fun a little expert system too. I never got until the end but I should finish once. Stef On Aug 14, 2012, at 7:26 AM, Lorenzo Schiavina wrote:

Hi Philip,

Doing nice formulas in Pharo would be of interest to me. And manipulating them even more (I am busy with that now).

So this make one project of interest for the community.

As for Geogebra as competition, these guys are now doing a ton of 3D (we use GG here with my wife, a maths teacher) and their DSL is pretty useful once mastered. I find myself constructing a lot of things from the little "command prompt" of theirs. That would be an interesting addition to DrGeo (and why not being GG-compatible on the commands).

Yes, should be easy to do. Dr. Geo already comes with a nice API to describe geometry object with Smalltalk. It could be hooked to an existing canvas.

DrGeo is Java-free, so where can we use it where Java is not fine?

I am not sure, but I think even ARM architecture comes with some sort of optimization for Java. Smalltalk is hard winner when the host architecture comes without OS. (i.e. SqueakNOS).

I'll look at what I can propose for engineers to work on. I'd add that a solver for constraints would be nice to have (like Simplex).

Do you have any ideas about case use of Simplex in Dr. Geo?

Also, a good thing to add to DrGeo is a window with a list of entities with their name and possibility to rename/change attributes from there. Once the things get complex, this is a godsend in GeoGebra...

Yes, I use to have that feature in Dr. Geo 1.1 many years ago. It will appear in someway in DrGeoII, but hopefully with Smalltalkish spirit, not sure how yet. Thanks Hilaire
