[Coin-discuss] Quadratic costs in OSI?

[Antonio Frangioni]

Hello.

We are embarking into a project where we need solving either (convex, 
separable) QPs or LPs.
I would love doing it through a OSISolver, and I'd expect this to be 
possible since all major
actual solvers under the interface in fact solve QPs as well. Yet, the 
OSISolver interface
does not allow for solving QPs.

I can hack my way through dynamic_casts<>() and solver-specific 
fragments, and this is
probably what I'll end up doing rather than writing my code for one 
specific solver, but of
course I'll be much happier with a completely standard solution. Any 
chance that the interface
could be revised in the near future for treating QPs? Any way in which 
I could help this
happening?
