[Clp] QP methods comparison

[armen nahapetyan]

 Hello everyone,

I tried to use Barrier method for solving QP problems and got a strange message at the end of some QP problems. Clp solves the problem but at the end it reports:
"Unknown objective -234.95 - 26 iterations time 8.542"
But with Clp default QP method, i.e. 'Reduced Gradient' Clp reports normal solution.

Does it mean that Barrier method is not enough robust?

Whether we can rely only on 'Reduces Gradient' for QP problems in general?

Thanks in advance,
Armen
