Not using IPOPT in bnb #2

Closed kibaekkim closed 8 years ago

kibaekkim commented 8 years ago

I would like to use binary bnb with option --nlp_engine IPOPT. But, MINOTAUR does not use Ipopt.

Minotaur has the option of using IPOPT for solving MINLPs and it seems working. The option is turned on the same way you have mentioned. Could you please write a little more about how exactly are you using it and what error are you getting.

Try this: bnb --qp_engine None --nlp_engine IPOPT

By default, if the relaxation is a QP, it will try to use a QP solver (BQPD). Hope it helps. Do let us know so that we can close this issue.

@ashutoshmahajan Yes. That works! Thanks!
