Version 5.3.1

Just a minor updated to v5.3 done in May 2015 to make it compile on more modern version of GCC compiler and operating systems.

Version 5.3

The v5.3 version was new as of 10/16/2005 and worked on versions of GNU/Linux and Apple's OS-X. The biggest differences from the previous 5.2 version was the addition of the finite-grid approximation algorithm. You can now read in a set of points from a file, you can force numeric rouding after each epoch, and a bunch of other niceties to help with infinite horizon convergence.

Version 5.2

This was new as of 10/10/2004 and has successfully been compiled in GNU/Linux and MAC OSX. Many minor additions and bug fixes are included, but the biggest change is the manner in which the command line optons are handled. The names have changed, and you can now use a configuration file.

Another big addition is the pomdp-tools executable, which is the home for POMDP utility programs. A few are implemented and a few are planned for the future.

Documentation for these changes exists, but is scattered and patchy, so it will not be available until I find the time to organized and revise it.

Version 5.0

This was new as of 12/17/2003 and has successfully been compiled in GNU/Linux and in MS Windows under Cygwin. The big change here is that is uses the autoconf/automake tools. There are also a few additional optimizations that were not present in version 4.0.
