Saving Intermediate Data



The values of the problem's variables,  the values of the Lagrange multipliers  associated with the problem's constraints  (if any) and the value of the penalty parameter  (if meaningful) are always saved in the SAVEDATA.dgif file at the end of optimization. This data can also be saved at regular intervals (expressed as SBMIN iterations) at the user's request. This is specified using the SAVE-DATA-EVERY keyword, with the desired interval following the keyword. A zero value means that the data is only saved at the end of the optimization. A default setting of

is used.
