---------------------------
Key: MATH-631
URL: https://issues.apache.org/jira/browse/MATH-631
Project: Commons Math
Issue Type: Bug
Reporter: Gilles
Fix For: 3.0
The following unit test:
{code}
@Test
public void testBug() {
final UnivariateRealFunction f = new UnivariateRealFunction() {
@Override
public double value(double x) {
return Math.exp(x) - Math.pow(Math.PI, 3.0);
}
};
UnivariateRealSolver solver = new RegulaFalsiSolver();
double root = solver.solve(100, f, 1, 10);
}
{code}
fails with
{noformat}
illegal state: maximal count (100) exceeded: evaluations
{noformat}
Using "PegasusSolver", the answer is found after 17 evaluations.
