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

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