orld.wolfram.com/BrentsMethod.html"> Brent algorithm.
The changes with respect to the original Brent algorithm are:
- the returned value is chosen in the current interval according to user specified {@link AllowedSolution},
- the maximal order for the invert polynomial root search is user-specified instead of being invert quadratic only
The given interval must bracket the root.
