COIN-OR::LEMON - Graph Library

source: lemon-0.x/src/test/dfs_test.cc @ 843:d56fad02dc55

  • BFD/DFS/Dijkstra compile test is done with skeleton::GraphSkeleton? graph and skeleton::ReadMap?.
  • 'skeleton::' is explicitely written instead of 'using namespace ...' in graph_test.cc
  • Output messages of type "makeRep(3)..." in unionfind_test.cc have been changed in order not to confuse compiler output parsers.
