Perhaps you should try some spelling variations:
"modified staffing optimization algorithmss" » "modified staffing optimization algorithms", "modified staffing optimisation algorithm", "modified staffing estimation algorithms", "modified caging optimization algorithmss"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective convolution algorithms") OR ("modified staffing optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified staffing optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("modified staffing optimization algorithmss"))*.
