Too general. Porting on a case-by-case

Are you referring to the SCG-Algorithm package in SCGStore?
The last version (1.28) essentially contains algorithm related to FCA. Is what you're
referring too?

Reported by alexandre.bergel on 2010-02-23 21:34:52

[seandenigris]

Partly yes. Actually it's anything related to algorithmic, which could be reused for
analysis. We should make a list 
of what is available on the store. Cyrille just started to look at the packages for
Clustering and Serialization used 
in distribution map.

=> There is The SCG-Algorithm bundle
    -> essentially contains the package FormalConceptAnalysis (that we should port
to pharo ) 
=> There is the HapaxDevelopment bundle, which contains:
    -> Clustering package (already port to Pharo (?))
    -> LinearAlgebra package (already port to Pharo (?))

then

    -> InformationRetrieval , according the moose website, we should port it

then

    => A lot of other packages (LinearAlgebra (more), HapaxVectorSpace , HapaxSemantic
,      
HapaxTrendDetection , HapaxExamples , HapaxTest ) for wich I don't know if we have
to port them.

Let's say that Clustering and LinearAlgebra have been "converted" to Pharo, that is
exported from VW as 
changeset (following the SCG procedure) then dumped in Pharo, with hacks in the changeset
so that Pharo 
does not complain/crash because of the platform change (I dont remember the details,
but there is annoying 
things there). For now it is not compatible with Pharo, and actually it crashes the
VM when tests are run, which 
I find amazing.

For the other parts: FormalConceptAnalysis would be nice, but I thought that Andy Kellens
and Gabriela 
would like to redo that too. We have to check with them.

InformationRetrieval sounds nice, I don't know what's behind but I guess that Adrian
K knows.

LinearAlgebra should perhaps be done in one pass, or at least converted in one pass.
All things related to 
Hapax... I would be glad but perhaps that's a lot of work. We should ask Adrian Kuhn
and use our tools to 
identify the most common parts to be retrieved.

Other things?

[seandenigris]

Tests from clustering and linearAlgebra no longer crash the VM. In fact, I just found
an infinite loop in the code, 
removed it, and now tests runs but don't freeze the image.

I have also 'converted' FormalConceptAnalysis to pharo and save it in the MooseAlgos
squeaksource repository.

I have ported the package InformationRetrieval. All tests are green in pharo. I saved
it in the MooseAlgos 
squeaksource repository. Let's look at the tests of LinearAlgebra ;)

Reported by cy.delaunay on 2010-02-26 13:24:07

[seandenigris]

All tests green for LinearAlgebra excepted for the class:
- MAFloatVectorTest. A primitive fail and I don't really know how to debug that.

Great work.

Condition for closing this bug: all tests green. Further bug should be addressed as
they appear

I moved this item to 4.0, since it is now basically what requests #357

Issue 357 has been merged into this issue.

Reported by simon.denier on 2010-04-06 18:32:30

[seandenigris]

All tests are now green.
I don't really know what was the use of MAFloatVector in VisualWorks, but when looking
to the code, it seems 
that its specificity is just to store Floats. 
The error came from the way floats were stored in VisualWorks or something related
to that.
The solution I provided is to implement MAFloatVector as MAArrayVector (which works
well), and just convert 
elements asFloat before storing them. If this is really the only thing it should do,
it seems to works, and all tests 
are green.

Reported by cy.delaunay on 2010-04-07 09:35:22

[seandenigris]

It seems ok, but you should post something about that on the Pharo list. Perhaps some
people will have better 
knowledge of the primitives concerned.
