Assuming the path first impact factor of, specific steps of the algorithm is and their respective impact factor is added to the path type (3), transform (3) as follows:
It is assumed that the first impact factor of the path, the algorithm implementation step is to influence factors and their paths are added to the equation (3), the conversion formula (3) as follows:
The first assumption here path influence factor, and specific implementation steps of algorithm is to take and their respective path impact factor is added to formula (3), (3) to transform:
