Simone Tripodi commented on SANDBOX-348:
----------------------------------------

Hi Thomas,
welcome in the graph brotherhood!!! ;)

Indeed, Boruvka is the less performant algorithm for the MST search, the reason to keep it
is that commons-graph aims to be a graph-pedia reference implementation, so users are free
to use the algorithm they prefer - I cannot immagine why they would prefer Boruvka instead
of Kruskal, but maybe there are conditions under which it could work.

That means that, if you are interested on graph/have any proposal, please feel free to fill
an issue and provide an impl! Have a look also to current open issues/task and, if you are
using eclipse, there are some type inference errors detected that need to be fixed ;)

As a side note: do you mind sharing the benchmarks you wrote on MST algos?

Many thanks in advance,
-Simo

> The class {{org.apache.commons.graph.spanning.Boruvka}} contains an empty implementation
of [Boruvka|http://en.wikipedia.org/wiki/Bor%C5%AFvka's_algorithm]'s algorithm, that needs
to be filled.
