Thank you very much for your code, which has given me a deeper understanding of heuristic algorithms. I have a question about your code.
1.Although you have divided the training set and the testing set, using heuristic algorithms for feature filtering using test data will not cause target data leakage，I don't quite understand this point, please clarify it.
