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