Optimizing in Alternate Mode

When you are optimizing in the alternate mode, you usually do not need to enter the ED_EXP module and manually change the weights of experiments that the computed results have not been fitted well with. Instead, after using OPTIMIZE_VARIABLES initially with no iterations, and listing the result with LIST_RESULT, simply run OPTIMIZE_VARIABLES again specifying, say, thirty iterations. Continue to optimize until your optimization seems to be going in the right direction, then set the optimizing variables’ starting values to their current values use RESCALE_VARIABLES before you turn alternate mode off by answering N at the SET_ALTERNATE_MODE prompt.
