org.apache.commons.math.analysis.solvers.BisectionSolver
public class BisectionSolver
Implements the bisection algorithm for finding zeros of univariate real functions.
The function should be continuous but not necessarily smooth.

@Deprecated public double solve(double min, double max, double initial) throws MaxIterationsExceededException, FunctionEvaluationException
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.
min
- the lower bound for the interval.max
- the upper bound for the interval.initial
- the start value to use
