[Coin-discuss] does CGL depend on CLP?

[Bo Jensen]

My point exactly. As a vendor I can say I have no trouble making sure our
software works with CBC, but last time I gave it a look, I realized the code
is specialized to Clp. The generic version ran so much slower, that I lost
interest. I think a fast version of Cbc that uses Osi (which might need a
rewrite) would be nice and in the spirit of the original idea of solver
independence.
