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 adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive 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 adaptive optimization algorithms") OR ("modified objective optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive optimization algorithms\") OR (\"modified objective optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified adaptive optimization algorithms ) OR ( modified objective optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive optimization algorithms") OR ("modified objective optimization algorithmss"))*.
