[Ipopt] 3.7.0 Restoration phase in the restoration phase failed.

[Stefan Vigerske]

Hi,

I experience similar behaviour. Several nlp's that solved fine with
Ipopt 3.6 give restoration failed trouble with Ipopt 3.7.

If I revert chgset 1485 (IpRestoConvCheck.cpp), it seems to work better.

Any clue why sometimes orig_theta_max should not be set to 0, even
though kappa_resto_ is 0? (whatever this means ;-))

Best,
Stefan
