Perhaps you should try some spelling variations:
"modified adam estimation algorithmss" » "modified adam estimation algorithms", "modified adam estimation algorithm", "modified adam optimization algorithms", "modified df estimation algorithmss", "modified near estimation algorithmss"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective 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 algorithmss") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithmss ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithmss") or ("modified multiobjective optimization algorithm"))*.
