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