fixed_mu_oracle:

Oracle for the barrier parameter when switching to fixed mode. $\;$
Determines how the first value of the barrier parameter should be computed when switching to the "monotone mode" in the adaptive strategy. (Only considered if "adaptive" is selected for option "mu_strategy".) The default value for this string option is "average_compl".
Possible values:

• probing: Mehrotra's probing heuristic
• loqo: LOQO's centrality rule
• quality-function: minimize a quality function
• average_compl: base on current average complementarity
