我们提出了基于简单但高效的想法的近似字符串匹配的新算法。首先,我们提出了一种用于与基于算术操作的不匹配的字符串匹配的算法,该算法在大多数实际情况下以线性最差的时间运行。这是一种搜索字符串的新方法。其次,我们为字符串与错误匹配的算法提供了基于分区的模式,该模式需要典型输入的线性预期时间。
We present new algorithms for approximate string matching based in simple, but efficient, ideas. First, we present an algorithm for string matching with mismatches based in arithmetical operations that runs in linear worst case time for most practical cases. This is a new approach to string searching. Second, we present an algorithm for string matching with errors based on partitioning the pattern that requires linear expected time for typical inputs.
