Abstract
The present invention significantly improves the performance of matching target file window partitions to source file window partitions in delta compression. In particular, the present invention enhances delta compression performance of delta compressors based on the idea of modeling a dataset with the frequencies of its n-grams and employs a method to compute good source and target window matching in linear time.
