Re: [Moose-dev] numerical method in smalltalk

SergeStinckwich
Hi all,

we talked recently on the moose mailing-list about having a more
robust library for doing mathematical stuff in Smalltalk
like SciPython or SciRuby (see below). If there is enough interested,
i'm wondering if we could propose a Google Summer of Code project
about that. I could write a draft for the project.

Regards,

Hi Serge,

There definitely is interest. If you volunteer for mentoring it would be great.

Cheers,

Yes sure i can do it. I can even maybe propose some local students.
Do you want to co-mentor ?

I would more want to see what can be done with it :). I have very little knowledge in this area and a bit too little time, but I can try to help.

Yes there is already the same version for Pharo/Squeak on Squeaksource.
There is actually a lot of code dispersed in several projects with
some duplication also.
The idea is to consolidate everything.

Yes in a perfect world, but having already something working on Pharo
is a first step.
After that people could adapt to other flavors if they want.

Hi Serge,

I have developed a package for fuzzy logic computation (in ST).
Do you think could be helpful?

Grazie

Yes!
It would be great to organize all the libraries we already have.

Dear Lorenzo,

yes might be interesting for SciSmalltalk. Is your code available
somewhere ? What is the licence of your code ?
Are you willing to integrate/adapt your work in a bigger package ?

serge not everything has to be in one package but in one repository
we could have

        Algo-FusyLogic
        Algo-Math
        Algo-…
        Algo-…

Hi Serge,

if you can understand Italian, you can see a presentation at:
http://www.edor.it/index.php?option=com_content&view=article&id=30&Itemid=65
This application has been developed in VSE, but a student of mine has
already done (a partial) porting in Squeak; he already told me that he
wanted to send it to Squeak community so, if you want, I can send it to you.
At present the code has no special license and I will be pleased to
integrate it into a bigger package with any kind of license.
My application has a specific fuzzyfication/defuzzyfication method but, if
you consider it useful, I can extend it to some other theoretical approach.
As a matter of fact, my application (not my student's) is an environment for
creating expert systems that have been used in many different fields
(medical, forecasting, sport, environment control).

Ciao

Yes sure you are right. I mean 1 repo in fact.

Yes please.

I think we should have the same licence than Pharo, MIT licence.

The idea of SciSmalltalk is to build a library not a tool. Maybe some
of part of your fuzzy operators you provide could be reused to be part
of this library.

Hi Serge,

I got in touch with Davide Arrigo, the guy who developed SqueakFuzzyWorld;
at present he is in Russia  and he will be back at the end of the month and
he will be pleased to send you directly the program application.
