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

maxEval - Maximum number of evaluations.f - Function to solve.min - Lower bound for the interval.max - Upper bound for the interval.allowedSolution - The kind of solutions that the root-finding algorithm may
accept as solutions.
MathIllegalArgumentException - if the arguments do not satisfy the requirements specified by the solver.
TooManyEvaluationsException - if
the allowed number of evaluations is exceeded.

startValue.
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 - Maximum number of evaluations.f - Function to solve.min - Lower bound for the interval.max - Upper bound for the interval.startValue - Start value to use.allowedSolution - The kind of solutions that the root-finding algorithm may
accept as solutions.
MathIllegalArgumentException - if the arguments do not satisfy the requirements specified by the solver.
TooManyEvaluationsException - if
the allowed number of evaluations is exceeded.
