Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithmsss" » "modified multiobjective optimization algorithmsss", "modified objective optimization algorithmsss", "modified multiobjective optimisation algorithm", "modified multiobjective optimization algorithms", "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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam estimation algorithm") OR ("modified multiobjective optimisation algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithm ) or ( modified multiobjective optimisation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithm") or ("modified multiobjective optimisation algorithmsss"))*.
