Comment 8 _ tboudreau 2009-11-18 08:00:19 UTC 
This is an experimental module, and the combo box actually says "(slow)" next to this algorithm.

Best I can think of is to remove the algorithm - it does slightly better layout, but it is very computationally expensive.

Would like to wrapper the various algorithms in the Jung open source project, which are from genuine academic research on graph theory (as opposed to something I hacked together with a bit of intuition).  This particular one is not really going to get fixed, though it may be removed.

Comment 10 _ tboudreau 2011-05-26 02:40:41 UTC 
Fixed in #72a13b51c032 (not a pretty fix - just disabled the combo box, since this layout is never going to perform well).
