Anthony Maidment created MATH-871: ------------------------------------- Summary: math3 SecantSolver can return Double.INFINITE Key: MATH-871 URL: https://issues.apache.org/jira/browse/MATH-871 Project: Commons Math Issue Type: Bug Affects Versions: 3.0 Reporter: Anthony Maidment Priority: Minor
In doSolve(), I had a situation in which f0 and f1, from computeObjectiveValue() on lines 77 & 78, were the same value. Then when it calculates the next appromixation at line 101: final double x = x1 - ((f1 * (x1 - x0)) / (f1 - f0)); The denominator is then zero, and the next approximation is Double.INFINITE. I was able to work around this in this particular instance by relaxing the accuracy requirements of the solver, although I haven't yet fully tested the downstream implications of this change. -- This message is automatically generated by JIRA.
