Perhaps you should try some spelling variations:
"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"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

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