Questions about the prompt selection about painter HOT 1 OPEN

Thank you for your excellent work. But I am confused about the details of obtaining a prompt via selection : “The first baseline is to obtain a better prompt via selection, that we traverse the whole training set in a heuristic manner and select the best-performing example pair for each task.” What does "a heuristic manner" mean? My understanding is to concatenate sample-specific features and all the prompt features, and then conduct the selection process. But could you provide more details about how does the selection process work? Is it weighted for each prompt?

Hi, have you soloved this problem?I couldn`t find any code about the "heuristic manner", or "learned prompt".
