Description

In class "DirectSearchOptimizer" (in package "optimization.direct"), the "optimize" method contains this code (at line 270):

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);
}

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.
