[Coin-discuss] Settings for Cbc with a Osi solver (not Clp)

[Ted Ralphs]

If all you want to do is testing, then I would suggest you use SYMPHONY 
instead of Cbc. SYMPHONY's implementation uses OSI in a completely 
solver-agnostic mode, so you shouldn't face any of the problems you do 
with Cbc. I don't think our configure script currently supports Mosek, 
but this would be easy to add if you're interested. We have a fairly 
well-developed unit test that should provide a pretty good stress test.

Cheers,

Ted
