optimize method. It is 0 if the method has not been
called yet.double getAbsoluteAccuracy()
v is a value returned by
one of the solve methods, then a root of the function should
exist somewhere in the interval (v - ε, v + ε).double getRelativeAccuracy()
getAbsoluteAccuracy(), but using
relative, rather than absolute error. If ρ is the relative accuracy
configured for a solver and v is a value returned, then a root
of the function should exist somewhere in the interval
(v - ρ v, v + ρ v).double getFunctionValueAccuracy()
v is
a value returned by the solver for a function f,
then by contract, |f(v)| should be less than or equal to
the function value accuracy configured for the solver.double solve(int maxEval,

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.MathIllegalArgumentException - if the arguments do not satisfy the requirements specified by the solver.TooManyEvaluationsException - if
