Has anybody out there worked with Williams and Zipsers "Real-time recurrent
learning algorithm"? [Connection Science, Vol 1, No 1].

We are currently trying to implement this algorithm, but have run into some
problems. We've got it to run succesfully on the various XOR problems
described, the "ab" problem (recognise the first "b" after an "a") and the
oscillation problems. What we can't seem to achieve is success for the Turing
machine problem. As this is perhaps the major result of the paper, it seems
important to duplicate it to reassure ourselves that everything is correct. Has
anyone else had success/failure with this problem? If success, would it be
possible to post your source? (We think we've got it right, but...)
