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

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 adam estimation algorithm\") OR (\"modified multiobjective estimation algorithmsss\"))~".
• Removing quotes may allow a broader search: (( modified adam estimation algorithm ) OR ( modified multiobjective estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithm") OR ("modified multiobjective estimation algorithmsss"))*.
