An updated version, 1.01, of the Goerge Mason University back prop
simulator, bps is now available via anonymous ftp from gmuvax2.gmu.edu.
This is a Unix system. The file bps.tar is a tar-formatted compressed version of
the GMU backprop simulator, tutorial(s) and sample files.  In order to
use it, you must tar it to de-archive it and then uncompress the
resulting 8 files. When you get that far, please read the brief file
readme.now before proceeding further.  

The current version, 1.01, of bps was released on Tuesday, Nov. 14 and
contains a fix to the transfer function derivative that was incorrect
if you used a symmetric transfer function, i.e. one with a range of
-M/2 to +M/2. AT present, the bug fix is only in the unix version --
we've had local network problems as well as no time. Please bear with us
on this. When you run the updated version, the version number appears on
the initial screen.

A SOURCE CODE license is now available. Please contact the undersigned
for details .
