a numerical methods package for Squeak (or other Smalltalks, like VisualWorks)

I found Didier Besset's book 'Object-Oriented Implementation of Numerical Methods' [1] online. I think the Smalltalk code package I am looking for came from this book/author. Perhaps it was called NumericalMethods, but in searching for this package I cannot find any code. Would anyone out here know of this package? I last used it around 2002 in VisualWorks. It had all sorts of distributions and infinite series and other function classes. Pretty awesome.

I am very interested to find it in order to do coronavirus infection distributions, with a Monte Carlo simulation and using a distribution to define the delay between infection time and the onset/appearance of symptoms and finally the delay from that onset to reporting to a hospital. The goal is I want to calculate Rt [2], for NC and VA, the effective reproductive rate in time. As calculated by the founders of Instagram, NC is now below 1 [3].

I appreciate any guidance you could give me to find this software. Gotta a link? I would love it!!

I use it in muO. Attached.

Also, it is part of SciSmalltalk according to the 2015 version of the book:

Awesome! Thanks so much! What is muO. Could you say a little about your uses?

Kindly,

Hi Stéphane,

I see the links to github hosted code. Can Squeak load these somehow? Hopefully not in Tonal format! How could I load these?

Kindly,
Robert

No idea about that, sorry - I just saw it this evening.

Well I do not really use it actually, it just happened that I have been
interested in probability densities at some point, and so I added the
code to the muO distribution to have everything at hand.

muO is a framework for musical composition:

Oh yeah, that's cool. I like your muO compositions! I barely know how to
lay a couple of instruments, still learning. We tried an online
bluegrass jam with Zoom and latency was certainly a problem with playing
together over the net. Isn't there a Squeak system of online music? I
had thought so.

I will explore the software you sent from Didier Besset. Awesome!!

Hi all!

The "numerical methods package for Squeak" reference reminds me of this rather recent proposal here:

FWIW I have implemented several computational geometry algorithms and
data structures for my current game.

Doubly-connected edges list, Voronoi tesselations (with the non-trivial
and very fast Fortune's algorithm), Polygon, Graphs (and A*/Djikstra), a
couple more stuff

I had a quick look and these packages
(https://github.com/PolyMathOrg/PolyMath) are indeed stored in Tonel
format. Metacello does not support that in Squeak at the moment.

I minimally ported the basic Monticello reading and writing of Tonel
to Squeak last year (not in Trunk), but it only allows you to load
packages from the file system one at a time through Monticello (no
dependency management and not even proper version management).

The Git Browser can also load Tonel projects (and manage versions in
Git, obviously), but it does not do dependency management either.
Moreover if this library is written for Pharo 7 and 8, it's fairly
sure that something will not work (or even load) out of the box in
Squeak. At least some porting effort would probably be required.

I've got a few utility packages maintained in Squeak (via MC):

- an interface to Lapack https://github.com/nicolas-cellier-aka-nice/smallapack/wiki

- an ArbitraryPrecisionFloat https://github.com/nicolas-cellier-aka-nice/arbitrary-precision-float/wiki/ArbitraryPrecisionFloat

- http://www.squeaksource.com/STEM.html

- http://www.squeaksource.com/MedianOfMedians.html

- http://www.squeaksource.com/Quaternion.html

I have some more unpublished, but no time to polish now...

Note that ArbitraryPrecisionFloat and Quaternion have been integrated into polymath, but might be a few versions behind

(they forked and renamed the classes, so...)

Cuis folks wanted to port Polymath, it might be easier to re-import from Cuis if that ever happen.

I also advise to follow https://github.com/len/Domains
