Perhaps you should try some spelling variations:
"modified notion estimation algorithmss" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion optimization algorithmss", "modified notion optimisation algorithms", "modified motion estimation algorithmss"
"modified sphere estimation algorithms" » "modified sphere estimation algorithm", "modified sphere optimization algorithms", "modified sphere optimisation algorithm", "modified pose estimation 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 sphere estimation algorithms") OR ("modified notion estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified sphere estimation algorithms\") OR (\"modified notion estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified sphere estimation algorithms ) OR ( modified notion estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified sphere estimation algorithms") OR ("modified notion estimation algorithmss"))*.
