mehrotra_algorithm:

Indicates if we want to do Mehrotra's algorithm. $\;$
If set to yes, Ipopt runs as Mehrotra's predictor-corrector algorithm. This works usually very well for LPs and convex QPs. This automatically disables the line search, and chooses the (unglobalized) adaptive mu strategy with the "probing" oracle, and uses "corrector_type=affine" without any safeguards; you should not set any of those options explicitly in addition. Also, unless otherwise specified, the values of "bound_push", "bound_frac", and "bound_mult_init_val" are set more aggressive, and sets "alpha_for_y=bound_mult". The default value for this string option is "no".
Possible values:

• no: Do the usual Ipopt algorithm.
• yes: Do Mehrotra's predictor-corrector algorithm.
