[Clp] question on gubVersion

[Fei Peng]

Hello clp community,

I have a question about the routine resolveGub and gubVersion included in osiClpSolverInterface and clpSimplexOther, respectively. I was thinking that this implements the GUB simplex by Dantzig, but it seems like gubVersion only shrinks the model, gives the model back to the solverinterface and let it do primal()? maybe I’m not reading it careful enough but could someone advise if this is what it’s supposed to do?

Thanks!
Fei
