[comp.ai.neural-nets] TSP on Hopfield network

boubez@caip.rutgers.edu (Toufic Boubez) (05/04/89)

	I am trying to implement a TSP on a Hopfield net, as described
in Hopfield and Tank's paper [Computing with Neural Circuits, Science,
vol 233, august 86]. I'm having trouble getting it to converge to the
right solution (to any solution!). Even when started from the right
solution, the net works itself back to a spurious state. I have tried
updating the nodes in a non-parallel fashion (it used to oscillate
before I did that), using new values from other nodes to update a
node's output. I have tried fiddling with the thresholds, the weight
values, etc...
	What I want to know is this: Has anyone tried it successfully,
and if so, what are the parameters that you used, and any other
hints/suggestions. Thanks a lot. Please e-mail to me.
