optimflex 0.1.6

• Replaced the quadratic example with the Rosenbrock example. Accordingly, removed dfp.R, which had failed to converge on this example in certain environments.

optimflex 0.1.5

Bug Fixes

• Fixed a convergence detection failure when the optimizer reaches the exact solution in a single step. A post-step gradient check has been added to all eight optimization algorithms.
• Replaced test-rosenbrock.R with test-quadratic.R to verify convergence on a simple quadratic function, consistent with the example in the dfp documentation.

optimflex 0.1.4

• Resubmission for CRAN.
• Removed tests/testthat/test-rosenbrock.R, which was inadvertently included in the previous submission and caused a convergence failure on M1 Mac (ATLAS BLAS)

optimflex 0.1.3

• Resubmission for CRAN.
• Replaced the example in ‘dfp.R’ with a simpler one.

optimflex 0.1.1

• Resubmission for CRAN.
• Fixed CRAN check errors in multirel examples and refined LaTeX documentation in dfp.R.
• Implements a flexible suite of optimization algorithms (BFGS, DFP, Dogleg, Newton, etc.).
• Features strict convergence control with eight combinable criteria.
• Includes a built-in mechanism for final Hessian positive definiteness verification.
