What C++ optimization Lib is used in quant job?

[featips]

Something like Matlab Fmincon or fminsearch, which can do constrained / unconstrained nonlinear optimization?

I mean, the C++ optimization lib used in industry, not just the google search results.

Thanks for inputs.

I've used knitro for some of my projects. You could download the free student/academic version from:
Artelys Optimization and modeling solutions

Thanks a lot, ramnik.

I am curious about how the portfolio optimization is implemented with C++ in those algorithm trading companies. They wrote their own 'efficient' library to do optimization calculation?

Thanks for replying. All these are commercial codes.

Anyone ever tried some open source libraries providing relatively nice optimization capability (certainly may not as powerful as those commercial ones)?

As a relative question; is GSL used in finance industry? I use is a lot in my PhD research and find it very useful.

Which packages in GSL that you used for optimization? I quickly browsed the reference manual, looks like the 'simulated annealing' and 'Multidimensional Minimization.' are relevant. However, looks like their functions are limited in term of solving nonlinear optimization (comparable to Matlab fmincon).

Anyone has experience of the open-source package opt++? How is its optimization capability? If it is good, I may spend some time delving into it. Bad thing (from its documents) is it does not support Visual studio.

bad thing? That might be the best thing!!!

So, you mean people don't like Visual studio?

I downloaded a student evaluation copy of Mosek.

First thing is test with example codes. In Visual studio, I set correctly 'additional library directories' and 'additional dependencies', then tried to compile and link the example code.

Unfortunately got following error:

------
1>LINK : fatal error LNK1104: cannot open file 'C:\Program Files (x86)\Mosek\6\tools\platform\win32x86\bin.obj'
------

Anyone know why this happen? Thanks.

not so much VS as people don't like Windows.

Are you sure that you set your libraries correctly? If your program compiled that error is usually due to a missing library.

The Mosek link libraries are only in folder ''C:\Program Files (x86)\Mosek\6\tools\platform\win32x86\bin'......so I think I set correctly

Found the reason:

I should input

"C:\Program Files (x86)\Mosek\6\tools\platform\win32x86\bin\mosek6_0.lib"

instead of

C:\Program Files (x86)\Mosek\6\tools\platform\win32x86\bin\mosek6_0.lib


Thanks Alain.
