reply: [Coin-ipopt] Ipopt C++ 3.0.0 print_level options

[文浩]

Hi,Xie Wei: 

　 Try it:
   Set both parameters in construction function to 'false' .
     SmartPtr<IpoptApplication> app = new IpoptApplication(false,false);
   


Hi, Andreas:

I am incorporating Ipopt in a branch-and-bound framework and wish to suppress any output to the screen from IPOPT, so as not to mess up with the iteration info from the branch-and-bound. Now, the question is that: what option should I use? I check the manual of C++, and it suggests me to set print_level to 0. However, even after doing so, the code still has a lot of printouts, namely, problem statistics, iterational information, and post solution statistics. I am wondering if IPOPT provides any convenient way, or I have to hack the source code.

Thanks,

Wei
