[Ipopt] Solver setting

[sungai kapuas]

Dear all,

I am a new user of Ipopt(MS Visual Studio 2005/2008/2010). After installing
and running for the first time, I was still not sure if I got the right
result. On my \src\Common\IpoptConfig.h it was not defined if it would
utilize MUMPS solver (neither 0 or 1 had been written), but on my console it
was written:

******************************************************************************
This program contains Ipopt, a library for large-scale nonlinear
optimization.
 Ipopt is released as open source code under the Common Public License
(CPL).
         For more information visit http://projects.coin-or.org/Ipopt
******************************************************************************

NOTE: You are using Ipopt by default with the MUMPS linear solver.
      Other linear solvers might be more efficient (see Ipopt
documentation).


This is Ipopt version 3.8.2, running with linear solver mumps.
....
etc.

Need some lights.
Thanks!

Regards,
Henry
