Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified adam estimation algorithmssss" » "modified adam estimation algorithm", "modified adam estimation algorithmsss", "modified adam optimization algorithmssss", "modified adam optimisation algorithmsss", "modified df estimation algorithmssss", "modified near estimation algorithmssss"

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

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