Perhaps you should try some spelling variations:
"modified adam estimation algorithmssss" » "modified adam estimation algorithms", "modified adam estimation algorithm", "modified df estimation algorithmssss", "modified near estimation algorithmssss"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

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