# Dakota Input File: herbie_shubert_opt_ego.in                          #s0
# Example of using EGO to find the minumum of the 5 dimensional version	#s0
# of the abitrary-dimensional/separable 'herbie' OR 'smooth_herbie' OR	#s0
# 'shubert' test functions			    		    	#s0
# NOTES:
#   Best known solution: objective f = -1.22112 at x = [1, 1, 1, 1, 1]
#   There are slightly poorer solutions in each orthant with x_i = +/-1
#   The regression test is currently protecting one such nearby solution
