Package: optimflex Type: Package Title: Derivative-Based Optimization with User-Defined Convergence Criteria Version: 0.1.8 Authors@R: person("Eunseong", "Cho", email = "bene@kw.ac.kr", role = c("aut", "cre")) Description: Provides a derivative-based optimization framework that allows users to combine eight convergence criteria. Unlike standard optimization functions, this package includes a built-in mechanism to verify the positive definiteness of the Hessian matrix at the point of convergence. This additional check helps prevent the solver from falsely identifying non-optimal solutions, such as saddle points, as valid minima.
