Hi,

I am interested in seeing the source code for the Maxima
implementation of Wang's algorithm to factor multivariate polynomials
over Z.

I know the source code is freely downloadable from Sourceforge, and
indeed I have downloaded it, but seem to be unable to open the .tar
file format that it is contained in.

Does anyone have just this implementation to hand, maybe in a text
file, or on a webpage somewhere?

Kind regards,
Jaymi

You have to unpack tar archive.

If you are on Linux (or any other Unix-like system) just use 'tar'
program:

tar -xzf maxima-5.20.1.tar.gz

On Windows WinZip shound do.

You can browse the source at:

http://maxima.cvs.sourceforge.net/viewvc/maxima/maxima

Is there some reason that you want Maxima code? If you are interested
in other implementations you can find FriCAS implementation of Wang
algorithm at:

http://fricas.svn.sourceforge.net/viewvc/fricas/trunk/src/algebra

The relevant files are 'leadcdet.spad.pamphlet', 'multfact.spad.pamphlet'
and 'mlift.spad.pamphlet'.

Many thanks both. Incidentally, you wouldnt happen to know where I
could pick up a Java implementation of Kaltofen's algorithm to factor
multivariates by any chance?

Perhaps not immediately relevant, but one general strategy
could be to use ABCL (Common Lisp implemented in Java)
and load symbolic algorithms written in Lisp.
