Perhaps you should try some spelling variations:
"modified made estimation algorithmss" » "modified made estimation algorithms", "modified made optimization algorithms", "modified pose estimation algorithmss", "modified male estimation algorithmss", "modified adam estimation algorithmss", "modified df estimation algorithmss"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

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 made estimation algorithmss\") OR (\"modified objective estimation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified made estimation algorithmss ) OR ( modified objective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made estimation algorithmss") OR ("modified objective estimation algorithm"))*.
