The invention uses Drosophila algorithm to optimize two parameters of support vector machine, on the basis of the improved ideal point method, the improved least square support vector machine model is used to evaluate the sustainability of a large number of power grid construction projects, in order toachieve the purpose of fast and accurate evaluation of a large number of similar projects, and reduce the complex expert scoring and calculation process.
