for the Kriging Model (test 3) changed correlations to correlation_lengths and used lengths approximately equal to what the global optimization method (direct) found for the Kriging rosenbrock test case with 100 build points
for the Kriging Model (test 3) changed correlations to correlation_lengths and used lengths approximately equal to what the global optimization method (direct) found for the Kriging rosenbrock test case with 100 build points

the kriging model (tests 2 and 3) now uses analytical derivatives (if we have them we might as well use them)
