# batch-large : a large-scale stress run for FrankWolfeSolver on big MCFBlock
# instances (the "goto" family, ~8k-65k arcs). Cross-check vs a :MILPSolver for
# the DQuad/Quad father. Expect this to take a while (tens of minutes): each
# goto10_8 run is several minutes, goto10_64 considerably more.
#
# usage:  ./batch-large [ <exe> ]      ( default ./FWS_test )
