title: 'optimflex: Derivative-Based Optimization with User-Defined Convergence Criteria'
version: 0.1.7
doi: 10.32614/CRAN.package.optimflex
abstract: 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.
