[Ipopt] Sparsity structure of the Hessian of the Lagrangian Function

Mon Jul 23 11:02:57 EDT 2012

Hello,
 just a quick info: if someone choose to avoid the hessian calculation
choosing the quasi-newton approach, is the sparsity structure of the
Hessian of the Lagrangian function still required by IPOPT?

Thanks,
  Antonello
