Therefore, trying to reduce the arity of idb. predicates is significative to improving the efficiency of query
因此，設法減少idb謂詞項數，對提高查詢效率是十分有意義的。 -
However, in search of the relevant data, the cost of generating additional tuples produced by logic program to which magic transformation is applied increases with the arity of idb ( intensional database ) predicates increasing
但是隨著遞歸idb （ intensionaldatabase ）謂詞的項的個數增大，經魔集轉換的邏輯程序為尋找與查詢相關數據而產生附加元組的開銷也會增大。 -

The central work of this paper is as follow : ( 1 ) a new factorizing optimization algorithm which reduce the arity of idb predicates by factorizing the logic program is presented magic transformation is applied to subprogram. moreover the decomposed subprogram can be implemented in parallel. therefore, it improves the efficiency of magic transformation
本文的主要工作如下： （ 1 ）提出一種新的分解優化演算法，它通過對邏輯程序進行分解，減少idb謂詞項的個數，再對分解后的各個子程序進行魔集轉換，而且分解后的各個魔程序可并行執行，從而提高魔集轉換的執行效率。
