extends AbstractUnivariateSolver
Class Inheritance
Imports
org.apache.commons.math3.util.FastMath, org.apache.commons.math3.exception.TooManyEvaluationsException
Implements the bisection algorithm for finding zeros of univariate real functions.

The function should be continuous but not necessarily smooth.
