Perhaps you should try some spelling variations:
"modified df estimation algorithmssssss" » "modified df estimation algorithms", "modified df estimation algorithm", "modified _ estimation algorithmssssss", "modified adam estimation algorithmssssss", "modified bi1 estimation algorithmssssss", "modified df estimation algorithmsssss"
"modified objective approximation algorithms" » "modified objective approximation 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 df estimation algorithmssssss") OR ("modified objective approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified df estimation algorithmssssss ) or ( modified objective approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df estimation algorithmssssss") or ("modified objective approximation algorithms"))*.
