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

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 optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified write estimation algorithmss\") OR (\"modified objective optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified write estimation algorithmss ) OR ( modified objective optimization algorithm ))*.
