Alex Herbert resolved NUMBERS-210.
----------------------------------
Fix Version/s: 1.4
Assignee: Alex Herbert
Resolution: Fixed
Fixed in commit:
55b5539c69d00b49d666020d483ead2c93e4a0e2
Added checks that the tolerances are finite positive; the function evaluation
is not NaN; and the initial [min, max] bracket contains finite values.
> BrentSolver has no validation of convergence accuracy or evaluated function
> value leading to possible non-convergence

> Key: NUMBERS-210
> URL: https://issues.apache.org/jira/browse/NUMBERS-210
> Project: Commons Numbers
> Issue Type: Bug
> Components: rootfinder
> Affects Versions: 1.3
> Reporter: Alex Herbert
> Assignee: Alex Herbert
> Priority: Minor
> Fix For: 1.4
>
>
> The BrentSolver does not validate that the relative, absolute or function
> value accuracy are positive and finite. This can lead to use of negative or
> NaN tolerance and no possible convergence.
> The evaluated function value may be computed as NaN. This invalidates any
> further convergence computation.
> Issue identified using a security scan.
