Today I have got reference to our new article in Optical Memory & Neural Networks journal. The article clearly describes the process of multi-dimensional binary optimization using Hopfield and Domain models of neural networks. The equations which establishes the relationship between the deepness of local minimum and the probability of its finding is also provided. I can send PDF to anyone who is interesting in this.
