Perhaps you should try some spelling variations:
"modified adaptive optimization algorithmsss" » "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified objective optimization algorithmsss", "modified adaptive quantization algorithmsss", "modified static optimization algorithmsss", "modified passive optimization algorithmsss"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective estimation algorithms") OR ("modified adaptive optimization algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified adaptive optimization algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified adaptive optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified adaptive optimization algorithmsss"))*.
