Perhaps you should try some spelling variations:
"modified staffing optimization algorithm" » "modified staffing optimization algorithms", "modified staffing optimisation algorithm", "modified staffing estimation algorithms", "modified caging optimization algorithm"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation 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 estimation algorithm") OR ("modified staffing optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective estimation algorithm ) or ( modified staffing optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithm") or ("modified staffing optimization algorithm"))*.
