## Class BisectionSingleRootFinder

• All Implemented Interfaces:
SingleRootFinder<Double,​Double>

public class BisectionSingleRootFinder
extends RealSingleRootFinder
Finds a single root of a function using the bisection method.

If a root of a function $f(x)$ is bounded by two values $x_1$ and $x_2$, then $f(x_1)f(x_2) < 0$. The function is evaluated at the midpoint of these values and the bound that gives the same sign in the function evaluation is replaced. The bisection is stopped when the change in the value of $x$ is below the accuracy, or the evaluation of the function at $x$ is zero.
