Subjective problems judgment based on BM algorithm and decision tree

This article did some innovations and exploration in the planning and exploiting course of individuation study system: in the subjective judgment module, we present the prefix and suffix BM algorithm. This algorithm imported the prefix comparative thought and the next character's information in QS algorithm, and when there are no matched characters in the matching course from right to left, it will consider the previous character. So through this algorithm can ensure the biggest moving distance, and this algorithm uses only two simple one-demensional array to avoid occupying too much memory space. Combining with data mining technology, this article did some exploratory research to the subjective problems judgment, designed the judgment algorithm based on decision tree, and realized the intelligentization of exercise system.
