From ef4a319984d22b88a9024ff523700d657621124d Mon Sep 17 00:00:00 2001 From: Carlo Zancanaro Date: Tue, 10 Jul 2012 13:44:21 +1000 Subject: Add the LEMON graph library source to the repo I'll likely be using it, so this just makes it easier to get to from elsewhere. If I end up not using it then I can just delete it. --- lemon/doc/images/bipartite_matching.eps | 586 +++++++++++++++++++++ lemon/doc/images/bipartite_partitions.eps | 114 ++++
