Transformational approaches transform a logic program into a term rewrite system (TRS) and then analyze termination of the resulting TRS instead. Thus, transformational approaches make all methods previously developed for TRSs available for logic program作者: tympanometry 時間: 2025-3-22 09:55 作者: 適宜 時間: 2025-3-22 15:43

Without the need to recompute from scratch, these rules remove not only the constraint but also undo all consequences of the rule applications that involved the constraint作者: 流出 時間: 2025-3-22 22:42
