Subject [jira] [Commented] (COLLECTIONS-431) Add useful collections from commons-graph
Date Tue, 10 Sep 2013 20:15:54 GMT

    [ https://issues.apache.org/jira/browse/COLLECTIONS-431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763442#comment-13763442

Thomas Neidhart commented on COLLECTIONS-431:
---------------------------------------------

Thanks for your effort!

There are some open questions though:

@DisjointSet:

 * it will require a unit test
 * how to integrate it into the collections framework / unit tests

@FibonacciHeap:

there is quite some discussion on stackoverflow about using a Fibonacci heap instead of the
standard PriorityQueue (which is a balanced binary heap) of java.util, but the conclusion
is mostly the same: fibonacci heaps have high asymptotic costs and can be tricky to implement.
Thus prior to included such an implementation we need figures about the performance and very
good test coverage.

also for CC.
