Rima: Linear Programming for Lua

[Geoff Leyland <geoff_leyland@...>]

Hi,

Version 0.02 of Rima, a symbolic math modelling package and binding to  
a number of linear programming [1] libraries, is available.

Documentation starts at http://www.incremental.co.nz/projects/ 
lua.html , development is now hosted on google code at http://code.google.com/p/rima/ 
 , and you can get the tarball from http://rima.googlecode.com/files/rima-0.02.tar.gz

If you're wanting to solve LPs from Lua, then as far as I know, Rima's  
your only choice (can anyone tell me otherwise?).  If you're not  
interested in LPs, then Rima's late-bound symbolic math is worth a  
look.  It might be pretty nifty, and at the very least it's a horribly  
complicated way of solving a simple problem.

Changes since the last version are a much richer late-bound handling  
of tables and table composition, improvements to syntax, and much  
better (but still not complete) documentation.  (BTW, the all the code  
snippets in the documentation make up part of the test suite thanks to  
doctest.lua!).

Coming up (this could take a while) I hope to move onto column-wise  
modelling and submodels, heading for some kind really nice  
composability system for models.

Any feedback would be much appreciated.


Cheers,
Geoff
