Research on the key issue of the process of the subjective items judging

摘要

There is an improved algorithm of the matching of prefix and suffix BM strings is proposed. The algorithm becomes more efficient by combining the prefix and the location information of the next character of the current window, trying more location movements with the existing information. Experiments show that this algorithm is better than BM algorithm. Furthermore, an algorithm of subjective items judging based on the BM is designed.
