dc639967c2 Fix localization formats used by ZeroException. 
The ZeroException preprends zero to the arguments. The {0} corresponds

1e7bce134f Adapt input files for "SimplexOptimizerTest" (unit tests). 
The current tests are "baseline" (2D) cases.
Further work should check degradation with increased dimensionality.

14ebd93426 Relax expected number of evaluations (unit test). 
Optimization is sensitive to the change from "AccurateMath" to "Math"
for computing the "pow" function used in "TestFunction.SUM_POW".

bdb4160b00 Add variance tests for zero weights 
Update javadoc for the behaviour when input weights are zero.

This issue was found when checking the sonar report for the variance
class which has a potential divide by zero if the weights sum to zero.

033c7e2c39 Correct verification of zero length values and weights 
This bug was found when checking the sonar report for the variance class
which uses MathArrays.verifyValues.

30aa597f1e sonar fix: Ensure checkFeasableCount is not negative. 
Change loop condition to 'i <= checkFeasableCount' from 'i <
checkFeasableCount + 1'

This ensures the loop to identify a new feasible column (RealMatrix
arxk) always executes at least once even with checkFeasibleCount at the
limit of 0 or Integer.MAX_VALUE.
