---------------------------------------

Hi,
I was wondering what is the current state for this JIRA? I am really interested in implementing Boruvka's algorithm, I just wanted to check out if the for-loop iteration issue has been fixed by now.

> This issue proposes the addition of a library method and an example for distributed minimum spanning tree in Gelly.
> The DMST algorithm is very interesting because it is quite different from PageRank-like iterative graph algorithms. It consists of distinct phases inside the same iteration and requires a mechanism to detect convergence of one phase to proceed to the next one. Current implementations in vertex-centric models are quite long (>1000 lines) and hard to understand.
> You can find a description of the algorithm [here | http://ilpubs.stanford.edu:8090/1077/3/p535-salihoglu.pdf] and [here | http://www.vldb.org/pvldb/vol7/p1047-han.pdf].
