Perhaps you should try some spelling variations:
"modified write optimization algorithms" » "modified write optimisation algorithm", "modified write estimation algorithms", "modified write estimation algorithm", "modified game optimization algorithms", "modified qoe optimization algorithms", "modified stage optimization algorithms"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation 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 one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified write optimization algorithms") OR ("modified one approximation algorithms")).
• Removing quotes may allow a broader search: (( modified write optimization algorithms ) or ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified write optimization algorithms") or ("modified one approximation algorithms"))*.
