FUNC
 Type of function to solve.public interface BracketedUnivariateSolver<FUNC extends UnivariateFunction> extends BaseUnivariateSolver<FUNC>
(univariate real) rootfinding
algorithms
that maintain a bracketed solution. There are several advantages
to having such rootfinding algorithms:
allowed solutions
. Other rootfinding
algorithms can usually only guarantee that the solution (the root that
was found) is around the actual root.For backwards compatibility, all rootfinding algorithms must have
ANY_SIDE
as default for the allowed
solutions.

A solver may require that the interval brackets a single zero root.
Solvers that do require bracketing should be able to handle the case
where one of the endpoints is itself a root.maxEval
