Subject [jira] [Created] (LUCENE-7309) Speed up Polygon2D construction
Date Wed, 01 Jun 2016 07:30:59 GMT
Adrien Grand created LUCENE-7309:

             Summary: Speed up Polygon2D construction
                 Key: LUCENE-7309
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor

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.
