Default Compiler Generated Methods | |
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called. | |

Method for computing the value of the barrier parameter that could be used in the current iteration.
Here, mu_min and mu_max are the lower and upper bounds on acceptable values for the barrier parameter. The new value of mu is returned in new_mu, and the method returns false if a new value could not be determined (e.g., because the linear system could not be solved for a predictor step).
Implemented in Ipopt::ProbingMuOracle, Ipopt::QualityFunctionMuOracle, and Ipopt::LoqoMuOracle.
