Correct, the above are supported in OS.

Correct, the above are not supported.

We also support Lindo. A trial version is at www.lindo.com. In 
OS/src/OSSolverInterfaces there is OSLindoSolver.cpp which we use to 
hook to the Lindo API.  You can also use Lindo to solve nonlinear 
programs. In our  OSInstance api there is a method to get the problem in 
  a postfix instruction list which you can feed to Lindo. I run and test 
Lindo daily on my Mac. I have also tested with Linux and Windows/cl with 
no problem.


/home/kmartin/COIN-OS/configure 
--with-lindo-lib="-L/home/kmartin/files/code/lindo/linux/lib -llindo 
-lmosek" --with-lindo-incdir=/home/kmartin/files/code/lindo/linux/include

Note also that The Mosek ApS now supports the OSiL format

http://www.mosek.com/fileadmin/products/5_0/tools/doc/html/pyapi/node022.html

but I have not tested this. Also Frontline Systems Solver Platform SDK 
currently  support OSiL for problem instance representation  of mixed 
integer linear programs.  See

http://www.solver.com/sdkplatformd.htm

I have not tested OSiL yet in the Frontline solver suite.


In summary, the MILP solvers we have personally tested to date are

Cbc
GLPK
SYMPHONY
CPLEX
Lindo


Probably the next solver I will add is Bonmin which is nonlinear integer 
and based on Ipopt which we also support.

Cheers,
