   - `FastShortcutNonlinearPolyalg()`: The default method. A polyalgorithm that mixes fast methods
     with fallbacks to robust methods to allow for solving easy problems quickly without sacrificing
     robustnes on the hard problems.
+  - `GeneralBroyden()`: Generalization of Broyden's Quasi-Newton Method with Line Search and
+    Automatic Jacobian Resetting. This is a fast method but unstable for most problems!
