Hi Deepak, the internal LS-OPT tolerance for assessing improvement in objective function is 1e-9, which is lower than the digits appearing in the table. Therefore, it is entirely possible that the first change was greater than 1e-9; you just don't see it in the table due to round off. Even without that you would have seen 4 repeated values (1st value + another 3 repetitions).
