Perhaps you should try some spelling variations:
"modified write estimation algorithmss" » "modified write estimation algorithm", "modified write optimization algorithms", "modified write estimation algorithms", "modified write optimization algorithmss", "modified write optimisation algorithms", "modified risk estimation algorithmss", "modified pose estimation algorithmss"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified write estimation algorithmss") OR ("modified objective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified write estimation algorithmss\") OR (\"modified objective estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified write estimation algorithmss ) OR ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified write estimation algorithmss") OR ("modified objective estimation algorithms"))*.
