Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified write optimization algorithmss" » "modified write optimization algorithms", "modified write optimisation algorithm", "modified write estimation algorithms", "modified game optimization algorithmss", "modified qoe optimization algorithmss", "modified stage optimization 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 optimization algorithmss") OR ("modified multiobjective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified write optimization algorithmss\") OR (\"modified multiobjective estimation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified write optimization algorithmss ) OR ( modified multiobjective estimation algorithm ))*.
