This is in response to a query for connectionist simulator code.
Within a month, one of the most comprehensive back propagation
simulators will be available to the general public.
Jay McClelland and David Rumelhart's third PDP publication,
Exploring Parallel Distributed Processing: A Handbook of Models, Programs,
and
Exercises will be available from MIT Press. C source code for the complete
backprop simulator, as well as others, is supplied on two MS-DOS format
5 1/4" floppy discs. The simulator, called BP, comes with the
necessary files to run encoder, xor, and other problems. It supports
multiple layer networks, constrained weight, and sender to receiver options.
The handbook and source code can be ordered from MIT Press at the address
below. The cost for both is less than $30. Why spend thousands more for
second best?

Another version of the BP simulator which is not yet generally available
to the public has been modified to take full advantage of the vector
architecture of the Convex mini-supercomputer. For certain applications
this gives speed increases of 30 times that of a VAX 11/780. A study is
underway to see how well BP will perform on a CRAY XMP-48.
