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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
