Robert Muir commented on LUCENE-7309: ------------------------------------- nice, thanks for testing. > Speed up Polygon2D construction > ------------------------------- > > Key: LUCENE-7309 > URL: https://issues.apache.org/jira/browse/LUCENE-7309 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Assignee: Adrien Grand > Priority: Minor > Attachments: LUCENE-7309.patch > > > Polygon2D.create recursively sorts on each dimension to build a tree. > However, it does not really need to sort the data, it just needs to compute > the median and partition other values around it, which can be performed in > O(n). If I am not mistaken, this would make Polygon2D.create run in O(n > log(n)) rather than O(n log^2(n)) today. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
