Hopfield neural networks have found applications in a broad range of disciplines [3-5] and have been studied both in the con-tinuous and discrete time cases by many researchers. Most neural networks can be classified as either continuous or discrete. In spite of this broad classification, there are many real-world systems and

In spite of this broad classification, there are many real-world systems and A Hopfield network is a simple assembly of perceptrons that is able to overcome the XOR problem (Hopfield, 1982).The array of neurons is fully connected, although neurons do not have self-loops (Figure 6.3).This leads to K(K − 1) interconnections if there are K nodes, with a w ij weight on each.

The Hopfield model consists of a network of N binary neurons. A neuron i is characterized by its state Si = ± 1. The state variable is updated according to the dynamics defined in Eq. (17.3). The task of the network is to store and recall M different patterns. The Hopfield model consists of N binary variables or bits, Si ∈ {+1,−1}.
