Perhaps you should try some spelling variations:
"modified choosing optimization algorithmss" » "modified choosing optimization algorithms", "modified choosing optimisation algorithm", "modified choosing estimation algorithm", "modified staffing optimization algorithmss", "modified choosing optimizer algorithmss", "modified caging optimization algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

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 algorithms") OR ("modified choosing optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) or ( modified choosing optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") or ("modified choosing optimization algorithmss"))*.
