Open source alternative to Mosek? [closed]

Question

Is there an open source alternative to Mosek?

Basically, I'm looking for large scale convex optimization solver packages.

Thanks!

EDIT:

Forgot to mention earlier, problem is non-linear; mostly quadratic, but occasionally may need non-quadratic constraints + non-quadratic objective

Answer 1

There are many packages, mostly with Matlab interfaces, like SDPT3, SeDuMi, and CVX. I believe the first two have their backends in C. The websites of these projects link to other packages. What language did you have in mind?
