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

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 algorithmss") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithmss ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithmss") or ("modified multiobjective optimization algorithms"))*.
