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/test/random_test.cc | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 lemon/test/random_test.cc (limited to 'lemon/test/random_test.cc') diff --git a/lemon/test/random_test.cc b/lemon/test/random_test.cc new file mode 100644 index 0000000..49dd8b6 --- /dev/null +++ b/lemon/test/random_test.cc @@ -0,0 +1,40 @@ +/* -*- mode: C++; indent-tabs-mode: nil; -*- + * + * This file is a part of LEMON, a generic C++ optimization library. + * + * Copyright (C) 2003-2009 + * Egervary Jeno Kombinatorikus Optimalizalasi Kutatocsoport + * (Egervary Research Group on Combinatorial Optimization, EGRES). + * + * Permission to use, modify and distribute this software is granted + * provided that this copyright notice appears in all copies.
