Predicting Future Years of USPE Conflicts via ASF (Addition-Subtraction Frequency) Method with Different Types, Different Input Numbers, and Consistency Analysis Twice

In our paper, we present distinct input-variable addition-subtraction frequency (ASF) method with different types to make predictions. Researching the future years of the US presidential election (USPE) conflicts of popular votes and electoral votes, to begin with, we utilize 3 input-variable ASF method with 3 types (i.e., full-traversal, unequal-half-traversal, and equal-half-traversal types), 5 input-variable ASF method with full-traversal, and 7 input-variable ASF method with fulltraversal to implement the numerical experiments, and make some comparisons of the prediction results. Additionally, except for the first normal consistency analysis, we regard the prediction results from the first consistency analysis as input data to make the second consistency analysis. Finally, 2028, 2052, 2064, 2068, 2080, 2128 and 2140 are predicted to be the most possible years when there are the USPE conflicts of popular votes and electoral votes (or more possibly saying, when there is a USPE conflict of popular votes and electoral votes).
