artificial intelligence (Or "Hopfield model") A kind of

neural network investigated by John Hopfield in the early

1980s. The Hopfield network has no special input or output

neurons (see McCulloch-Pitts), but all are both input and

output, and all are connected to all others in both directions

(with equal weights in the two directions). Input is applied

simultaneously to all neurons which then output to each other

and the process continues until a stable state is reached,

which represents the network output.
