英文摘要：

Sorting is a kind of special problem in computer science. The flexibility of whose algorithm design tactics leads to the diversity of sorting algorithms. Based on the formal method PAR （partition-and-recur）, an automated sorting algorithm generation is studied. The algebraic property of sorting problem is described, generic type components and algorithm components are formally developed, and domain specific language and a formal algorithm generative model are designed. Through replacing the generic identifiers with a few concrete operations a series of known and unknown sorting algorithms, such as quick sort, heap sort, shell sort, and increment select sort, etc., are automatically generated, which is supported by the enhanced program generation system. Through the super framework and underlying components, the reliability and productivity of domain specific algorithm have dramatically improved.
