August 25, 2004 spudd version 3.4.0 Fixed a bug in the parser which didn't allow nested conjunction and disjunction structures ([* ...] and [+ ....]) in the dds. Beta support for solving POMDPs using fast point-based value iteration. Not fully tested yet. email jhoey if you'd like details.

July 5, 2004 spudd version 3.3.2 Added the option to generate policies with only a single action for each state. This option *must* be used in situations with more than about 50 actions. see the README for details.

May 26, 2004 spudd version 3.3.1 Fixed a memory leak! Spudd now runs in about 1/20 of the memory!

April 4, 2004 spudd version 3.3 Updated the parser so subdiagrams (d\ ds) can be specified separately and re-used. Also, CPTs do not need to be normalized - this gets done automatically. Added some functions f\ or simluating (sampling from the posterior). See the (updated) README in spudd-3.3/Spudd/doc/ for more information and how to specify a inp\ ut file

Feb 16th, 2003: Spudd version 2.0 ! includes support for multi-valued variables.
Spudd v2.0 is fully backwards compatible with the old input data format, but allows files in a new mutli-valued variable format.
