Phil Steitz resolved MATH-556.
------------------------------
Resolution: Fixed
Fixed in r1088895.
> CMAESOptimizer constructor should copy rather than reference input arrays
> -------------------------------------------------------------------------
>
> Key: MATH-556
> URL: https://issues.apache.org/jira/browse/MATH-556
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: Nightly Builds
> Reporter: Phil Steitz
> Priority: Minor
> Fix For: 3.0
>
>
> The CMAESOptimizer constructors take array arguments but do not copy the
> input arrays. The current implementation does not write to the input arrays,
> but client code could, making the API contract ambiguous. This practice
> should in general be avoided unless the arrays are meant to be in/out
> parameters or they are expected to be very large. Neither of these
> conditions appear to hold in CMAESOptimizer, so the constructors should be
> modified to copy the input arrays.
