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.
