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

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

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