No, there is no such way. But I'm thinking about adding it. It's hard to add
it yourself, since the code is pretty intricate. Also, if D is not positive
semidefinite, the solver is not guaranteed to even find a local minimum. It
might as well crash in such a case.

Best,
Bernd.

Betreff: [cgal-discuss] Quadratic program initial values

Hello,

Is there a way to set the initial value of the variables when constructing a
quadratic program?
If not, can you please show me where I can change that in CGAL source code?

My matrix D is not positive-semidefinite, so I may need to restart the
optimization with different starting points to find the global minimum.

Thank you,

Fernanda
