Aiming at the impact of different candidates in the United States on the Chinese and American economies, this paper established a projection pursuit comprehensive evaluation model based on improved butterfly optimization algorithm to analyze the US economy and economy. We establish project pursuit comprehensive evaluation model based on improved butterfly optimization algorithm. First, perform data preprocessing on the 9 evaluation index data to eliminate the influence of outliers; then, establish a projection pursuit evaluation model for high-dimensional data. Secondly, use improved butterfly optimization algorithm to solve the model, and finally it is obtained that without considering the epidemic situation, Trump’s score is 8.76 and Biden is 7.89. When considering the epidemic situation, Trump’s score is 5.23, and Biden scores As 6.17. Further sensitivity analysis of the solution results proves that the model is stable.
