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

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