[Ipopt] IPOPT Checking Necessary and Sufficient Conditions ?

[Anil Rao]

Yes, IPOPT does check the sufficient conditions.  Amongst other tests,
IPOPT checks to see that the projected gradient is zero and the projected
Hessian is also positive (semi)-definite in order to determine if the
solution is locally optimal.
