Probing (Mehrotra) mu oracle — port of
IpProbingMuOracle.{hpp,cpp}. Phase 10.
Given the affine-step complementarity mu_aff and current mu,
the probing rule chooses
sigma = min((mu_aff / mu)^3, sigma_max)
mu_new = sigma * muper IpProbingMuOracle.cpp:117-121 and the standard Mehrotra
predictor-corrector formula.
