Kinoshita > Priority: Major > Fix For: 1.9.1 > > Attachments: improvement.patch > > Time Spent: 1h 20m > Remaining Estimate: 0h > > The calculation made by the LevenshteinDistance class can often be made > faster, when the class in initialized with a threshold, and when the distance > is found to be larger than the threshold. In those cases, it is often not > necessary to iterate through the whole string, since a lower bound for the > result can be established after each iteration. If that lower bound is larger > than the threshold, the method can simply exit early with the same result as > without this improvement. > A patch with the proposed change is attached to this issue. -- This message was sent by Atlassian Jira (v8.3.4#803005)
