, generally choose the Sigmoid function , then you can get the second formula (2):Through the above two formulas, we can analyze the calculation process of output results in BP neural network. Each neuron receives the stimulus Yi and then the weighted accumulation (weighted Wji ) is completed after the XJ is produced, and then stimulated by the activation function of yJ , The next layer of neurons to which it is connected is passed, and, in turn, results are eventually output.We will then analyz

N,k Analysis: N,k is very small, l large, considering the enumeration, enumerating the number of points with the shortest short-circuit as I a[i] For two points i,j if DI=
