Dual bounds provided to SNDlib:

dual bound contributor submission date additional information
365020.00 Christian Raack 06.11.2006 edge-flow formulation, CPLEX 10.0 plus flow-cutset inequalities, time limit 1h

Note: we encourage you to submit dual bounds to a problem if you have them. However, in contrast to primal solutions, we cannot check dual bounds for validity, which is why dual bounds are only listed here together with their contributor.
