From Wikipedia, the free encyclopedia Mehrotra's predictor–corrector method in optimization is a specific interior point method for linear programming. Although there is no theoretical complexity bound on it yet, Mehrotra's predictor–corrector method is widely used in practice. b s 0 − Δ [citation needed].
