[Coin-discuss] accessing the Clp solver from Cbc/Clp

[Kish Shen]

Hi,

For the interface to OSI/Coin solvers that I am developing, I am hoping to do 
most things via the OSI interface, so that we can access as wide a range of 
solvers as possible, and then provide `specialised' code to improve 
performance/functionality for specific solvers, such as Cbc/Clp.
I have a couple of questions about this:

1 Is there a way to determine which linear solver is being used from either 
Cbc or OsiCbcSolverInterface?
 
2 If Clp is being used, is there anyway to access the solver directly (i.e. 
the ClpModel pointer)? I would like to do this because OsiSolverInterface 
does not seem to allow me to do everything I want to do, e.g. accessing the 
basis for the LP problem, or use the barrier method to solve the problem.

Thanks in advance for any information/help!

Cheers,

Kish
