Perhaps you should try some spelling variations:
"modified objective estimation algorithmssss" » "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithmssss", "modified objective allocation algorithmssss"
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "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 objective estimation algorithmssss") OR ("modified adaptive optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithmssss\") OR (\"modified adaptive optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithmssss ) OR ( modified adaptive optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithmssss") OR ("modified adaptive optimization algorithms"))*.
