One-time initialization in "DirectSearchOptimizer"
--------------------------------------------------
Key: MATH-376
URL: https://issues.apache.org/jira/browse/MATH-376
Project: Commons Math
Issue Type: Bug
Reporter: Gilles
Priority: Minor
In class "DirectSearchOptimizer" (in package "optimization.direct"), the
"optimize" method contains this code (at line 270):
{code}
if (startConfiguration == null) {
// no initial configuration has been set up for simplex
// build a default one from a unit hypercube
final double[] unit = new double[startPoint.length];
Arrays.fill(unit, 1.0);
setStartConfiguration(unit);
}
{code}
I think that this has the consequence that it is impossible to call "optimize"
a second time, where one would like to solve a problem with a different
dimension.
